Ras-related protein Rab-39A (RAB39A)
The protein contains 217 amino acids for an estimated molecular weight of 25007 Da.
Plays a role in the maturation and acidification of phagosomes that engulf pathogens, such as S.aureus and M.tuberculosis. Plays a role in vesicular trafficking. Plays a role in the fusion of phagosomes with lysosomes. Negatively regulates LPS-induced autophagosome formation in macrophages possibly by implicating PI3K (PubMed:24349490). May be involved in multiple neurite formation (By similarity). (updated: Sept. 12, 2018)
