|WB||1/10000 - 1/50000. Detects a band of approximately 138 kDa (predicted molecular weight: 138 kDa).|
FunctionSeems to play a role in the development or function of the kidney glomerular filtration barrier. Regulates glomerular vascular permeability. May anchor the podocyte slit diaphragm to the actin cytoskeleton. Plays a role in skeletal muscle formation through regulation of myoblast fusion.
Tissue specificitySpecifically expressed in podocytes of kidney glomeruli.
Involvement in diseaseDefects in NPHS1 are the cause of nephrotic syndrome type 1 (NPHS1) [MIM:256300]; also known as Finnish congenital nephrosis (CNF). A renal disease characterized clinically by proteinuria, 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 and progress to end-stage renal failure.
Sequence similaritiesBelongs to the immunoglobulin superfamily.
Contains 1 fibronectin type-III domain.
Contains 8 Ig-like C2-type (immunoglobulin-like) domains.
Developmental stageIn 23-week-old embryo found in epithelial podocytes of the periphery of mature and developing glomeruli.
modificationsPhosphorylated on tyrosine residues.
Cellular localizationCell membrane. Predominantly located at podocyte slit diaphragm between podocyte foot processes. Also associated with podocyte apical plasma membrane.
