ANP32B Multifunctional protein working as a cell cycle progression factor as well as a cell survival factor. Required for the progression from the G1 to the S phase. Anti-apoptotic protein which functions as a caspase-3 inhibitor. Has no phosphatase 2A (PP2A) inhibitor activity. Exhibits histone chaperone properties, stimulating core histones to assemble into a nucleosome. Belongs to the ANP32 family. Expressed in heart, lung, pancreas, prostate and in spleen, thymus and placenta. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
