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.

Scientific Data Images for Human/Mouse/Rat Kirrel3/NEPH2 Antibody
Detection of Rat Kirrel3 by Western Blot.
Western blot shows lysates of rat embryonic hippocampal neuron. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human/Mouse/Rat Kirrel3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4910) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for Kirrel3 at approximately 120 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.Detection of Human Kirrel3/NEPH2 by Western Blot
Kirrel3 protein detection in adult human skeletal muscle. A – Western Blot results obtained with anti-human Kirrel3 antibody directed toward intracellular region of Kirrel3 on skeletal muscle lysates obtained from adult human males at baseline, days one and two after completion of a DHR exercise protocol. S = subject B – Western blot results from blocking peptide experiment. The antibody in A was incubated with blocking peptide before being added to membrane containing skeletal muscle lysates obtained from adult human males at baseline and one and two days post completion of a DHR exercise protocol. C – A second commercial antibody directed towards the extracellular domain of Kirrel3 was used on a selection of lysates obtained from adult human male skeletal muscle day1 or 2 post completion of the downhill running exercise bout. Ponceau staining was performed on membranes to demonstrate transfer and equal protein loading.
