Background

Giantin or Golgin subfamily B member 1 is a protein that in humans is encoded by the GOLGB1 gene. GOLGB1, also known as Giantin and Macrogolgin, is a 360 to 400 kDa member of the Golgin protein family. GOLGB1 is an integral component of the Golgi membrane that associates with the cytoskeleton. It may be involved in both forming intercisternal cross-bridges that mediate stacking in Golgi complexes, and in reorganizing the complexes after they fragment during mitosis. GOLGB1 has also been identified as an autoantigen in chronic rheumatoid arthritis, and in the autoimmune disease Sjoegren syndrome. Human GOLGB1 is 3259 amino acids (aa) in length, and over aa 1596-1702, shares 92% and 91% sequence identity with its mouse and rat orthologs, respectively.

Function

Key regulator of transforming growth factor beta (TGFB1, TGFB2 and TGFB3) that controls TGF-beta activation by maintaining it in a latent state during storage in extracellular space. Associates specifically via disulfide bonds with the Latency-associated peptide (LAP), which is the regulatory chain of TGF-beta, and regulates integrin-dependent activation of TGF-beta. Able to outcompete LTBP1 for binding to LAP regulatory chain of TGF-beta. Controls activation of TGF-beta-1 (TGFB1) on the surface of activated regulatory T-cells (Tregs) . Required for epithelial fusion during palate development by regulating activation of TGF-beta-3 (TGFB3) (By similarity) .
