这个基因编码的蛋白质是鸟苷三磷酸（GTP）代谢酶Ras超家族的成员编码蛋白在造血细胞中表达，在造血细胞中起负调节细胞生长和存活的作用。该基因可能在白血病和淋巴瘤中发生过突变或表达错误非霍奇金淋巴瘤的染色体易位发生在该位点与3号染色体上的b细胞cll/淋巴瘤6（bcl6）之间，导致融合转录产物的产生。5'未翻译区域的选择性剪接导致编码相同蛋白质的多个转录变体。

The protein encoded by this gene is a member of the Ras superfamily of guanosine triphosphate (GTP)-metabolizing enzymes. The encoded protein is expressed in hematopoietic cells, where it functions as a negative regulator of cell growth and survival. This gene may be hypermutated or misexpressed in leukemias and lymphomas. Chromosomal translocations in non-Hodgkin's lymphoma occur between this locus and B-cell CLL/lymphoma 6 (BCL6) on chromosome 3, leading to the production of fusion transcripts. Alternative splicing in the 5' untranslated region results in multiple transcript variants that encode the same protein.
