這個基因編碼的蛋白質是鳥苷三磷酸（GTP）代謝酶Ras超家族的成員編碼蛋白在造血細胞中表達，在造血細胞中起負調節細胞生長和存活的作用。該基因可能在白血病和淋巴瘤中發生過突變或表達錯誤非霍奇金淋巴瘤的染色體易位發生在該位點與3號染色體上的b細胞cll/淋巴瘤6（bcl6）之間，導致融合轉錄產物的產生。5'未翻譯區域的選擇性剪接導致編碼相同蛋白質的多個轉錄變體。
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.
