It may also be known as: Serum deprivation-response protein; PS-p68; Phosphatidylserine-binding protein; Cavin-2; phosphatidylserine binding protein; CAVIN2; SDR. The encoded protein has an amino acid length of 425 and a mass of 47.2 kDa. Other isoforms may exist. SDPR is a member of the PTRF/SDPR family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Frog, Chicken.
