ATPase Family, AAA Domain Containing Protein 3C (ATAD3C)

ATPase family AAA domain-containing 3A is a novel anti-apoptotic factor in lung adenocarcinoma cells.AAA domain-containing 3A (ATAD3A) is a member of the AAA-ATPase family.

Three forms of ATAD3 have been identified: ATAD3A, ATAD3B and ATAD3C. Expression of ATAD3A was detected by reverse transcription-polymerase chain reaction, immunoblotting, immunohistochemistry and confocal immunofluorescent microscopy. ATAD3A is the major form expressed in LADC. Silencing of ATAD3A expression increased mitochondrial fragmentation and cisplatin sensitivity. Serum deprivation increased ATAD3A expression and drug resistance. These results suggest that ATAD3A could be an anti-apoptotic marker in LADC.
