关于 XG

功能概要

该基因编码 XG 血型抗原，位于 X 染色体短 (p) 臂的假常染色体边界。三个 5' 外显子位于假常染色体区域，其余外显子位于 X 特异性末端。在假常染色体边界的 Y 染色体上发现了该基因的截短副本。它被转录，但预计不会产生 Y 染色体特异性基因产物。已发现该基因编码不同亚型的可变剪接转录物变体。[RefSeq 提供，2008 年 11 月]

This gene encodes the XG blood group antigen, and is located at the pseudoautosomal boundary on the short (p) arm of chromosome X. The three 5' exons reside in the pseudoautosomal region and the remaining exons within the X-specific end. A truncated copy of this gene is found on the Y chromosome at the pseudoautosomal boundary. It is transcribed, but not expected to make a Y-chromosome specific gene product. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.
