The Ras superfamily of GTPases, which can be subdivided into the Ras, Rho/Rac, Sar, Rab, ARF and Ran subfamilies, controls multiple aspects of cell function, including cytoskeletal rearrangement, nuclear signaling and cell growth. The Ras superfamily of GTPases function as regulated switches that toggle between a biologically active GTP-bound and an inactive GDP-bound form. This activation is catalyzed by guanine nucleotide exchange factors (GEFs). MCF2L2 (MCF.2 cell line derived transforming sequence-like 2), also known as DRG, is a 1,114 amino acid protein that contains one spectrin repeat, one PH domain, one DH domain and one CRAL-TRIO domain. Expressed at high levels in brain and also present in testis and pancreas, MCF2L2 is thought to function as a GEF, catalyzing the activation of target GTPases. Variations in the gene encoding MCF2L2 may be associated with an increased susceptibility to type 2 diabetes. Multiple isoforms of MCF2L2 exist due to alternative splicing events. |
