TUBA1A encodes the human gene, Tubulin alpha 1a. It may also be known as: Tubulin alpha-1A chain; Tubulin B-alpha-1; Tubulin alpha-3 chain; Alpha-tubulin 3; tubulin, alpha, brain-specific; B-ALPHA-1; LIS3; TUBA3; tubulin, alpha 1a. The encoded protein has an amino acid length of 451 and a mass of 50.1 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Frog.
