該基因編碼一個多域蛋白，參與胚胎發育過程中細胞連接的信號和組織該基因與t（6；11）（q27；q23）易位的急性髓系白血病（americ myeloid leukemia，all-1）基因融合。另外，編碼不同亞型的剪接轉錄變體已經被描述用于該基因，然而，并不是所有的都已經被完全描述出來了。[由RefSeq提供，2011年5月]
This gene encodes a multi-domain protein involved in signaling and organization of cell junctions during embryogenesis. It has also been identified as the fusion partner of acute lymphoblastic leukemia (ALL-1) gene, involved in acute myeloid leukemias with t(6;11)(q27;q23) translocation. Alternatively spliced transcript variants encoding different isoforms have been described for this gene, however, not all have been fully characterized.[provided by RefSeq, May 2011]
