該基因編碼的蛋白是一種轉錄調節因子和腫瘤蛋白，可能參與造血、凋亡、發育、細胞分化和增殖。編碼蛋白可與ctbp1、smad3、crebbp、kat2b、mapk8和mapk9相互作用。該基因可與aml1基因發生易位，導致該基因的過度表達和白血病的發生。已經發現了一些編碼一些不同亞型的轉錄變體。[由RefSeq提供，2011年3月]
The protein encoded by this gene is a transcriptional regulator and oncoprotein that may be involved in hematopoiesis, apoptosis, development, and cell differentiation and proliferation. The encoded protein can interact with CTBP1, SMAD3, CREBBP, KAT2B, MAPK8, and MAPK9. This gene can undergo translocation with the AML1 gene, resulting in overexpression of this gene and the onset of leukemia. Several transcript variants encoding a few different isoforms have been found for this gene. [provided by RefSeq, Mar 2011]
