Transmembrane BAX inhibitor motif-containing protein 4 is a protein that in humans is encoded by the TMBIM4 gene.[5][6][7] It is also known as human Golgi anti-apoptotic protein (hGAAP) due to its function and sub-cellular localization.

Function

Human GAAP [8] is a protein present in the Golgi that helps regulate apoptosis, a form of programmed cell death. By regulating the fluxes of Ca+2, an increase of GAAP can help prevent apoptosis.[9][10] GAAP is also involved in promoting cell migration[11] [12] and has been identified as a novel Golgi cation channel.[13] Other GAAPs can be found in all eucaryotes analyzed and in some bacteria. A viral GAAP (vGAAP) can also be found in some strains of vaccinia virus, the live vaccine used to eradicate smallpox.
