这个基因编码一种蛋白质，可能在前mrna剪接中起作用。染色体易位（X；1）（p11；q21）导致该基因与TFE3（基因id 7030）融合，与乳头状肾细胞癌有关PRCC-TFE3融合蛋白在癌组织中表达，可能与基因反式激活改变有关这种融合蛋白也与细胞周期的破坏有关。
This gene encodes a protein that may play a role in pre-mRNA splicing. Chromosomal translocations (X;1)(p11;q21) that result in fusion of this gene to TFE3 (GeneID 7030) have been associated with papillary renal cell carcinoma. A PRCC-TFE3 fusion protein is expressed in affected carcinomas and is likely associated with altered gene transactivation. This fusion protein has also been associated with disruption of the cell cycle.[provided by RefSeq, Aug 2010]
