Detection of Human Rit2 by Western Blot. Western blot shows lysates of human brain (cerebellum) tissue and human brain (hypothalamus) tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human Rit2 Monoclonal Antibody (Catalog # MAB6094) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Rit2 at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

GTP-binding protein Rit2 (Rit2; also Rin, Ras-like protein expressed in neurons, Ras-like without CAAX) is a 25 kDa member of the small GTPase superfamily and Ras family. Human Rit2 is 217 amino acids (aa) in length. Like all small G-proteins, Rit2 contains five highly conserved domains (G1-G5) and acts as a molecular switch by alternating an active GTP-bound form and an inactive GDP-bound form. There are two isoforms for Rit2. Isoform 1 is the long form. Isoform 2 has an 11 aa substitution for residues 143‑153 found in isoform 1 and a deletion of aa 154‑217. Rit2 is expressed exclusively in neurons. In addition, Rit2 binds calmodulin through a C‑terminal binding motif.
