Genes of interest to start annotating

This table represents a GO annotation starting list for this project showing the UPKB accession number for each gene and an approximate number of papers from a quick pubmed search for the gene name and the species and kidney function. Please feel free to start annotation whenever suits you and to add comments for discussion and completion date etc. If you come across further genes of interest please add them to the list on this wiki and send them to me so that I can update the xls gene list.

Involvement in kidney function Mouse Human Rat Chicken Xenopus Laevis Xenopus tropicalis Completed Comments*
Tesc Q9JKL5/ 1 Q96BS2/ 1 IPI00769039/ - A0AVX7/ 1 Q5U554/ 1 Q0V9B1/ - yes [YAF] PMID 19345287 state (pg 278, top right) that a lack of kidney expression by immunocytochemistry in mice embryos suggests that TESC might not have a significant role in kidney[RF].

PMID 11145610 states that TESC mRNA was present in mouse fetal testis restricted to the testicular cords but was not expressed in the ovary or metanephros. Col9a3 was present at low levels in female and male gonads at 11.5 days and thereafter upregulated in male gonads only and expression was restricted to testicular cords; Renin was localized in cells of the interstitium and cells at the border between the gonad and mesonephros (from abstract and Fig.6 A-L ISH) [YAF 26/08/09]

Slc23a1 Q9Z2J0/ 3 Q9UHI7/ 7 Q9WTW7/ 4 B9VMA9 (Slc23a2)/ 1 -/ 1 B0JZG0 (Slc23a2)/ - yes [YAF] There's no chicken or Xenopus Slc23a1 TrEMBLs yet: Slc23a2 entries are closest match, tho according to PMID 17689499, Slc23a1 (SVCT1) is expressed in epithelial systems (eg kidney), whereas Slc23a2(SVCT2) is more expressed in metabolic tissues (eg pancreas, brain, adrenals)[RF].

PMID 17258485 demonstrates presence of chicken-specific SVCT1 mRNA (via RT-PCR)in both cultured and native proximal tubule cells using primers derived from chicken ESTs and hence demonstrates vitamin C transport [YAF 28/08/09]

Ctnnb1 Q02248/ 49 P35222/ 84 Q9WU82/ 15 O42486/ 1 P26233/ 4 Q28GC2/ - yes [YAF] RG Wnt signaling target Sept 2010
Lamb1-1 P02469/ 1 P07942/ 1 P15800(Lamb2)/ - O57484/ - Q5XHI6/ - B3DLV1/ - yes [YAF 10/11/09] PMID 12631063 shows that murine laminin-1 is normally downregulated in early stages of glomerular development and is reexpressed in a murine model of Alport disease becoming concentrated in the glomerular basement membrane projections typical of this disorder - maintains expression of collagen alpha1 and alpha2(IV). hence collagen alpha3(IV) is involved in glomerular basement membrane development since in col4a KO mice there is an abnormal GBM characteristic of immature glomeruli. PMID 16041630 shows abnormal basement membrane in the inner ear and kidney of the Mpv17-/- KO mice, therefore Mpv17 is involved in glomerular basement membrane development and inner ear development. PMID 16631359 is just an article on production of mAb against mouse laminin alpha and beta chains but shows expn in adult kidney [YAF 10/11/09].
Egr1 P08046/ 3 P18146/ 9 P08154/ 6 O73691/ - Q6GQH4/ - A4II20/ - yes [YAF 17/11/09] No kidney expression or function for Xenopus Egr1. Induced during mesoderm induction [REF 16/11/09]. Not much for mammalian kidney expression or function. PMID 8530399 shows transcriptional activation/repression of murine egr1 by WT1. PMID 12689920 shows increase in murine egr1 expression by insulin and glucose in murine vascular endothelial cells. PMID 14979875 investigates interaction between human NFATc1 and Sp1/Sp3/EGR1 regulating MT-MMP transcription by glomerular mesangial cells. [YAF 17/011/09]

For mouse Id2: PMID 12456807 - not kidney specific but important for mammary gland alveolar epithelial cell differentiation (NTR). PMID 8922523 looks at mRNA expn of mouse Id1/2/3/4 during mouse embryogenesis - Id1-3 seem to be expressed during development of multiple tissues inc. lung/kidney/heart/teeth/cartlage and bone/ vascularization/glandular structures; Id4 seems only to be expressed in the developing neuronal tissues and in ventral epithelium of developing stomach - did not annotate into P2G as it is mRNA expn data?[YAF 24/11/09]

Expression patterns for Xenopus and mouse (PMID 17875669) suggest a function for Irx3 in patterning the nephron by specifying pronephron intermediate tubule and metanephron Henle's loop fates respectively. The function in frogs is confirmed with knock-outs [RF, 15/09/09].

PMID 18715948 looks at Irx1 and Irx2 in Xenopus pronephros development. .

Xwt1 plays a role in glomus (pronephric filter system) development; may repress tubule (and duct?) gene expression in the region of the pronephros fated to become the glomus PMID 8725280 PMID 9758706 [REF 24/11/09]. Most mammalian WT1 papers I have annotated are mainly investigating it's transcription repressor activity of certain genes. PMID 19050011 investigates involvement of WT1 and BASP1 in podocyte differentiation (NTR) [YAF 26/11/09].

Osr1/Odd1 Q9WVG7/ 6 Q8TAX0/ 4 B0K011/ - E1BWE8/ 2 P86413/ Q66JF8/ - yes (H, R, B and M marked as PAC) [YAF 05/04/2011] (Not on GUDMAP LoH list)(Found when doing a PM search on kidney development). PMID 16790474 and PMID 18835385 have led to many new terms needing to be created. Also interestingly, reports that in wild type mice there are 2 types of mesonephric tubules that develop: anterior tubules fuse with the nephric duct and posterior tubules that remain unfused with the duct. In Odd1 mutant mice (+ Wt1 mutants - PMID 9118800) the anterior fused tubules differentiate but the posterior tubules are absent [YAF 23/11/09].

Comments / Discussion points

  • Comparative paper? PMID 19345287 cites mouse, chicken and xenopus orthologs
  • Drosophila use Malpighian tubules for excretion so there is no loop of Henle as such. However there do seem to be common aspects of renal function in flies and vertebrates as indicated in these recent papers:
  • The kidneys of larval and adult amphibians do not develop loops of Henle (LOH). However, the layout of the amphibian pronephros (the fully functional embryonic kidney, which is indispensable for larval life) is very similar to the mammalian adult metanephric kidney, and contains tubules similar to those that make up the LOH of mammals (PMID 17875669).

For SLC23A1-HUMAN (Q9UHI7)

1. NTR item #2846310: to request a new term 'sodium-dependent L-ascorbic acid transmembrane transporter activity' as mentioned in PMID 10631088 (IDA) for the function of SVCT1/SLC23A1 (Q9UHI7). I'm not sure if it would be a child of either GO:0022857 transmembrane transporter activity or of GO:0008523 sodium-dependent multivitamin transmembrane transporter activity? I also think perhaps that there should be another new term 'L-ascorbic acid transmembrane transporter activity' as a child of GO:0022857 transmembrane transporter activity and GO:0015229 L-ascorbic acid transporter activity and then the term 'sodium-dependent L-ascorbic acid transmembrane transporter activity' could be a child of that (too)? - Midori added: sodium-dependent L-ascorbate transmembrane transporter activity GO:0070890 [YAF 01/09/09]

2. NTR item #2849019: to request new term transepithelial ascorbic acid transport (or transepithelial ascorbate transport) , as a child of GO:0070633 transepithelial transport, for annotation of the SVCT1 and SVCT2 proteins as described in the recent publication PMID 18417304. -Midori added transepithelial L-ascorbic acid transport GO:0070904 [YAF 03/09/09]

(Podocytes (or visceral epithelial cells) are cells of the visceral epithelium in the kidneys and form a crucial component of the glomerular filtration barrier, contributing size selectivity and maintaining a massive filtration surface. Adjacent podocytes interdigitate to cover the basal lamina which is intimately associated with the glomerular capillaries, but the podocytes leave gaps or thin filtration slits. The slits are covered by slit diaphragms which are composed of a number of cell-surface proteins including nephrin, podocalyxin, and P-cadherin, which ensure that large macromolecules such as serum albumin and gamma globulin remain in the bloodstream. Small molecules ie: water, glucose, and ionic salts are able to pass through the slit diaphragms and form an ultrafiltrate which is further processed by the nephron to produce urine. Podocytes are also involved in regulation of glomerular filtration rate (GFR). When podocytes contract, they cause closure of filtration slits. This decreases the GFR by reducing the surface area available for filtration) Requested 02/12/09 SF 2907403[YAF 02/12/09].
