General description

SUN domain-containing protein 2 (UniProt Q9UH99; also known as Protein unc-84 homolog B, Rab5-interacting protein, Rab5IP, Sad1/unc-84 protein-like 2) is encoded by the SUN2 (also known as FRIGG, KIAA0668, RAB5IP, UNC84B) gene (Gene ID 25777) in human. It is a single-pass nuclear envelope transmembrane protein that is highly expressed in heart, lung, and muscle. It has a predicted transmembrane domain and a C-terminal region with similarity to the S. pombe spindle pole body protein Sad1. It may also facilitate a nuclear-centrosomal interaction required for nuclear migration and anchorage. It anchors chromosome movement in the prophase of meiosis and is required for telomere attachment to nuclear envelope and gametogenesis. SUN2 protein may also function on endocytic vesicles as a receptor for RAB5-GDP and participate in the activation of RAB5. Slight overexpression of SUN2 protein is seen in heart tissues form patients with congenital heart defects.
