該基因的產物是mads/mef2家族dna結合蛋白的一員。該蛋白被認為可以調節基因表達，包括平滑肌肌球蛋白重鏈基因的表達。該區域經歷了相當多的選擇性剪接，轉錄本支持兩個不重疊的位點（基因ID 729991和100271849）以及跨越兩個位點的大量通讀轉錄本（注釋為基因ID 4207）。該蛋白的幾個亞型表達于該位點或基因4207上注釋的一些通讀轉錄本。[由RefSeq提供，2014年1月]
The product of this gene is a member of the MADS/MEF2 family of DNA binding proteins. The protein is thought to regulate gene expression, including expression of the smooth muscle myosin heavy chain gene. This region undergoes considerable alternative splicing, with transcripts supporting two non-overlapping loci (GeneID 729991 and 100271849) as well as numerous read-through transcripts that span both loci (annotated as GeneID 4207). Several isoforms of this protein are expressed from either this locus or from some of the read-through transcripts annotated on GeneID 4207. [provided by RefSeq, Jan 2014]
