Other synonyms may include: actin binding protein 280, alpha-filamin, endothelial actin-binding protein, filamin A alpha, non-muscle filamin, ABPX, and CVD1. It is encoded by the FLNA gene to yield a protein 2647 amino acids in length and 280.7 kDa in size. However, there are up to 2 reported isoforms. The protein is categorized into the Filamin family. Versions of OPD1 are present in other organisms, including: Mouse, Rat, Frog.
