Also known as NEPH1
Summary
KIRREL1 (kirre like nephrin family adhesion molecule 1, HGNC:15734) is a protein-coding gene on chromosome 1q23.1, encoding Kin of IRRE-like protein 1 (Q96J84). Required for proper function of the glomerular filtration barrier.
NEPH1 is a member of the nephrin-like protein family, which includes NEPH2 (MIM 607761) and NEPH3 (MIM 607762). The cytoplasmic domains of these proteins interact with the C terminus of podocin (NPHS2; MIM 604766), and the genes are expressed in kidney podocytes, cells involved in ensuring size- and charge-selective ultrafiltration (Sellin et al., 2003 [PubMed 12424224]).

- A striking finding in this study is the lack of contribution of NEPH1, NPHS1, and NPHS2 genes in 15 Asian families with steroid-resistant nephrotic syndrome. (PMID:16968734)
- common variants in LRRC7, KIRREL, NPHS2 and ACTN4 do not appeear to contribute to susceptibility to diabetic nephropathy in Finnish patients with type 1 diabetes (PMID:17968527)
- Neph1 but not nephrin specifically binds to adaptor protein Grb2 and tyrosine kinase Csk in a phosphorylation-dependent manner. (PMID:18258597)
- Neph1-Nephrin proteins bind the Par3-Par6-atypical protein kinase C (aPKC) complex to regulate podocyte cell polarity (PMID:18562307)
- tyrosine phosphorylation of Neph1 mediated by Fyn results in significantly increased Neph1 and ZO-1 binding, suggesting a critical role for Neph1 tyrosine phosphorylation in reorganizing the Neph1-ZO-1 complex. (PMID:18922801)
- Localization of Neph1 to the podocyte cell membrane is altered in the presence of mutant Myo1c, and is actin dependent. Knockdown of Myo1c inhibits Neph1 membrane localization. Neph1 is critical for the maintenance of glomerular function. (PMID:21402783)
- Neph1-CD adopts a global shape in solution, and its interaction with ZO-1 involves multiple sites. (PMID:22262837)
- maintaining high levels of Neph1 at the membrane using a podocyte cell line overexpressing chimeric Neph1 increased the ability of podocytes to resist PAN-induced injury and PAN-induced albumin leakage (PMID:24554715)
- Analysis of interaction surfaces between NEPH1 and MYO1c led to the identification of a critical residue in Neph1 involved in binding to Myo1c. Indeed, a point mutant from this site abolished interaction between Neph1 and Myo1c. (PMID:27044863)
- Mutations in KIRREL1, a slit diaphragm component, cause steroid-resistant nephrotic syndrome. (PMID:31472902)
- Overexpression of kin of IRRE-Like protein 1 (KIRREL) as a prognostic biomarker for breast cancer. (PMID:32534710)
- Cell adhesion molecule KIRREL1 is a feedback regulator of Hippo signaling recruiting SAV1 to cell-cell contact sites. (PMID:35177623)
- Transmembrane protein KIRREL1 regulates Hippo signaling via a feedback loop and represents a therapeutic target in YAP/TAZ-active cancers. (PMID:36044856)

Function. Required for proper function of the glomerular filtration barrier. It is involved in the maintenance of a stable podocyte architecture with interdigitating foot processes connected by specialized cell-cell junctions, known as the slit diaphragm. It is a signaling protein that needs the presence of TEC kinases to fully trans-activate the transcription factor AP-1.
Subunit / interactions. Interacts with TJP1/ZO-1 and with NPHS2/podocin (via the C-terminus). Interacts with NPHS1/nephrin (via the Ig-like domains); this interaction is dependent on KIRREL1 glycosylation. Homodimer (via the Ig-like domains). Interacts when tyrosine-phosphorylated with GRB2.
Subcellular location. Cell membrane.
Tissue specificity. Abundantly expressed in kidney. Specifically expressed in podocytes of kidney glomeruli.
Post-translational modifications. Phosphorylation probably regulates the interaction with NSH2. Phosphorylated at Tyr-605 and Tyr-606 by FYN, leading to GRB2 binding. N-glycosylated.
Disease relevance. Nephrotic syndrome 23 (NPHS23) [MIM:619201] A form of nephrotic syndrome, a renal disease clinically characterized by severe proteinuria, resulting in complications such as hypoalbuminemia, hyperlipidemia and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. Some affected individuals have an inherited steroid-resistant form that progresses to end-stage renal failure. NPHS23 is an autosomal recessive form characterized by onset of proteinuria in the first or second decade of life, and variable outcome. Some patients have normal renal function after many years, whereas others may progress to chronic kidney disease. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the immunoglobulin superfamily.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 186 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
