該基因編碼的蛋白是鋅指轉錄因子，含有一個n端poz結構域。該蛋白作為一種序列特異性的轉錄抑制因子，已被證明調節b細胞stat依賴性il-4應答的轉錄。這種蛋白質可以與多種poz蛋白相互作用，poz蛋白具有轉錄輔壓作用。該基因在彌漫性大細胞淋巴瘤（dlcl）中常發生易位和過度突變，可能參與dlcl的發病機制。另外，已經發現了編碼不同蛋白質亞型的剪接轉錄變體。[由RefSeq提供，2015年8月]
The protein encoded by this gene is a zinc finger transcription factor and contains an N-terminal POZ domain. This protein acts as a sequence-specific repressor of transcription, and has been shown to modulate the transcription of STAT-dependent IL-4 responses of B cells. This protein can interact with a variety of POZ-containing proteins that function as transcription corepressors. This gene is found to be frequently translocated and hypermutated in diffuse large-cell lymphoma (DLCL), and may be involved in the pathogenesis of DLCL. Alternatively spliced transcript variants encoding different protein isoforms have been found for this gene. [provided by RefSeq, Aug 2015]
