Sestrin 2 (SESN2)

Sestrin-2 is a member of the sestrin family of PA26-related proteins. The encoded protein may function in the regulation of cell growth and survival. This protein may be involved in cellular response to different stress conditions.The full-length SEST2 cDNA encodes a deduced 480-amino acid protein predicted to be a compact globular domain protein composed predominantly of alpha-helical structures. SEST2 has several potential serine-threonine and tyrosine phosphorylation sites, most of them located within the alpha helices. Northern blot analysis revealed a 3.9-kb transcript expressed at low to moderate levels in most tissues examined. In vitro translation of the cDNA resulted in a protein with an apparent molecular mass of about 60 kD.
