MCF2L encodes a guanine nucleotide exchange factor that interacts specifically with the GTP-bound Rac1 and plays a role in the Rho/Rac signaling pathways. A variant in this gene was associated with osteoarthritis. Alternative splicing results in multiple transcript variants. MCF2L (MCF. Cell Line Derived Transforming Sequence Like) is a Protein Coding gene. Diseases associated with MCF2L include Atypical Autism and Osteoarthritis. Among its related pathways are p75 NTR receptor-mediated signalling and Phospholipase-C Pathway.
