Background: Kirrel3/NEPH2

Kirrel3 (Kin of IRRE-like protein 3 precursor; also NEPH2) is a 95-120 kDa member of a small family of podocin binding molecules. Kirrel3 is found on podocytes and olfactory sensory neurons and likely plays a role in cellular adhesion. Kirrel3 is 778 amino acids in length. It is a type I transmembrane (TM) glycoprotein that contains a 514 aa extracellular region (aa 22-535) with five C2 type Ig like domains (aa 48-515) plus a 222 aa cytoplasmic tail. Kirrel3 binds itself as well as nephrin, podocin and ZO-1. Kirrel3 is shed by MMPs, generating a soluble urinary fragment that is 25 kDa smaller than the TM form. Two variant isoforms exist. One has an alternate start site at Met34, while the second shows a 35 aa substitution for aa 566-778. Over aa 1-535, human Kirrel3 is 98% aa identical to mouse Kirrel3.
