该基因编码一种在淋巴组织中优先表达的组织限制性核转录激活因子这种蛋白的分离最初定义了一个高度保守的核转录因子laf4/mllt2基因家族，可能在淋巴系统发育和肿瘤发生中发挥作用。在一些所有的病人中，这个基因被发现与mll基因融合。已经发现了编码不同蛋白质的多个选择性剪接转录变体。[由RefSeq提供，2008年7月]
This gene encodes a tissue-restricted nuclear transcriptional activator that is preferentially expressed in lymphoid tissue. Isolation of this protein initially defined a highly conserved LAF4/MLLT2 gene family of nuclear transcription factors that may function in lymphoid development and oncogenesis. In some ALL patients, this gene has been found fused to the gene for MLL. Multiple alternatively spliced transcript variants that encode different proteins have been found for this gene.
