MEF2B

该基因的产物是mads/mef2家族dna结合蛋白的一员。该蛋白被认为可以调节基因表达，包括平滑肌肌球蛋白重链基因的表达。该区域经历了相当多的选择性剪接，转录本支持两个不重叠的位点（基因ID 729991和100271849）以及跨越两个位点的大量通读转录本（注释为基因ID 4207）。该蛋白的几个亚型表达于该位点或基因4207上注释的一些通读转录本。[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]
