该基因编码一个激活转录因子，属于ATF亚家族和BZIP（碱性区亮氨酸拉链）家族。它通过调节下游靶基因的表达来影响细胞生理过程，下游靶基因与生长、存活和其他细胞活动有关。在丝氨酸/苏氨酸激酶、环腺苷酸依赖性蛋白激酶A、钙调素依赖性蛋白激酶I/II、丝裂原和应激激活蛋白激酶和细胞周期蛋白依赖性激酶3（CDK-3）的激酶诱导结构域中，该蛋白在丝氨酸63处磷酸化。其磷酸化增强其反式激活和转录活性，并促进细胞转化。该基因与16号染色体上的fus或22号染色体上的ewsr1易位融合，在血管瘤样纤维组织细胞瘤和透明细胞肉瘤中产生嵌合蛋白。这个基因在6号染色体上有一个假基因。[由RefSeq提供，2010年8月]
This gene encodes an activating transcription factor, which belongs to the ATF subfamily and bZIP (basic-region leucine zipper) family. It influences cellular physiologic processes by regulating the expression of downstream target genes, which are related to growth, survival, and other cellular activities. This protein is phosphorylated at serine 63 in its kinase-inducible domain by serine/threonine kinases, cAMP-dependent protein kinase A, calmodulin-dependent protein kinase I/II, mitogen- and stress-activated protein kinase and cyclin-dependent kinase 3 (cdk-3). Its phosphorylation enhances its transactivation and transcriptional activities, and enhances cell transformation. Fusion of this gene and FUS on chromosome 16 or EWSR1 on chromosome 22 induced by translocation generates chimeric proteins in angiomatoid fibrous histiocytoma and clear cell sarcoma. This gene has a pseudogene on chromosome 6. [provided by RefSeq, Aug 2010]
