Alternatively spliced transcript variants of the FMNL2 gene encoding different isoforms have been described.[1] The full length FMNL2 (FRL3) protein (1092 amino acids-NCBI Reference Sequence: NP_443137.2[3]) is regulated through autoinhibition, and may become activated through Rho proteins.[4] The FMNL2 gene is expressed in multiple human tissues.[5]
Function
Formin-like protein 2 is a formin-related protein. Formin-related proteins have been implicated in morphogenesis, cytokinesis, and cell polarity.[1]
Clinical significance
FMNL2 expression is considerably higher in colorectal cancer tumors compared to normal tissue.[6]
