ATPase Domain 3B (ATAD3B) is a protein that in humans is encoded by the ATAD3B gene. [citation needed] ATAD3 is part of the AAA protein family. The function of ATAD3B is not yet well understood by the scientific community. In humans the gene is located at 1p36.33.

Function[edit]

Human Embryonic Stem Cells

ATAD3B is associated with the mitochondria. The C terminus is anchored in the mitochondrial inter membrane space.[1]

The protein is linked with the pluripotency of stem cells. The ATAD3A gene is targeted by c-Myc[1] which is one of four factors needed to create induced pluripotent stem (i-PS) cells from mouse embryonic fibroblasts(MEFs).[2]

Its expression is linked to cell cycle function and tumor growth.[3] When ATAD3B was overexpressed, cell duplication took an extra three hours by spending a longer time in G1 phase.[3] Abnormal expression levels of ATAD3B has been linked to chemoresistance. Overexpression of ATAD3B was the found to be the strongest factor in breast cancer survival rates.[4]

Characteristics[edit]

A mutation in the stop codon means that ATAD3B has a 62 amino acid longer UTR.[5]
