There are a number of ELISA Kits available for the measurement of Ral GTPase activating protein, alpha subunit 1, another term for the human protein, Ral GTPase activating protein catalytic alpha subunit 1. Other synonyms may include: ral GTPase-activating protein subunit alpha-1, GAP-related interacting protein to E12, GTPase activating Rap/RanGAP domain-like 1, Ral GTPase activating protein alpha subunit 1 (catalytic), GARNL1, GRIPE, and RalGAPalpha1. It is encoded by the RALGAPA1 gene to yield a protein 2036 amino acids in length and 229.8 kDa in size. However, there are up to 7 reported isoforms. Versions of Ral GTPase activating protein, alpha subunit 1 are present in other organisms, including: Mouse, Rat, Zebrafish, Frog, Chicken.
