BLCAp基因突变与药物因子介绍
这个基因编码一种通过刺激细胞凋亡来减少细胞生长的蛋白质。选择性剪接和选择性启动子的使用导致编码相同蛋白质的多个转录变体。这个基因在大脑中留下印记，在那里不同的转录变体从每个父母等位基因表达。上游启动子起始的转录变异体优先从母体等位基因表达，而散布的NNAT基因（GeneID:4826）下游起始的转录变异体则从父系等位基因表达该位点的转录本也可能经过A-I编辑，导致蛋白质N-末端三个位置的氨基酸变化[由RefSeq提供，2015年11月]
This gene encodes a protein that reduces cell growth by stimulating apoptosis. Alternative splicing and the use of alternative promoters result in multiple transcript variants encoding the same protein. This gene is imprinted in brain where different transcript variants are expressed from each parental allele. Transcript variants initiating from the upstream promoter are expressed preferentially from the maternal allele, while transcript variants initiating downstream of the interspersed NNAT gene (GeneID:4826) are expressed from the paternal allele. Transcripts at this locus may also undergo A to I editing, resulting in amino acid changes at three positions in the N-terminus of the protein. [provided by RefSeq, Nov 2015]
