MIA2（MIA SH3 domain ER export factor 2），癌症关联基因，基因ID：4253，该基因编码内质网中的受体，在乳糜微粒前和极低密度脂蛋白前（pre-vldls）的输出中起作用。从该基因产生的转录物主要有三类：黑色素瘤抑制活性2-特异性转录物、cTAGE家族成员5-特异性转录物和包括这两种转录物（TANGO1样或TALI）外显子的转录物此外，这些转录物的选择性剪接导致编码多个亚型的多个转录物变体。[由RefSeq提供，2016年9月]This gene encodes s receptor in the endoplasmic reticulum， which plays a role in the export of large pre-chylomicrons and pre-very low density lipoproteins (pre-VLDLs). Three major classes of transcripts are generated from this gene- melanoma inhibitory activity 2-specific transcripts， cTAGE family member 5-specific transcripts and transcripts that include exons from both these transcript species (TANGO1-like or TALI). Additionally， alternative splicing in these transcripts results in multiple transcript variants encoding multiple isoforms. [provided by RefSeq， Sep 2016]。
