酪氨酸激酶 (ＴＫ)是造血细胞信号传导的主要成分 ,在调节细胞增殖及分化方面具有重要意义 ,其异常高表达与多种造血系统肿瘤的发生有关。ＢＭＸ是在人骨髓细胞ＲＮＡ中发现的一种新的非受体ＴＫ基因 ,定位于染色体Ｘｐ2 2 .2 ,其ｍＲＮＡ长度 2 .7ｋｂ ,编码一相对分子质量为
Tyrosine kinase (TK) is the main component of hematopoietic cell signaling and plays an important role in the regulation of cell proliferation and differentiation. The abnormally high expression of tyrosine kinase (TK) is associated with the occurrence of many hematopoietic tumors. BMX is a new non-receptor TK gene found in human bone marrow cell RNA. It locates on chromosome Xp2 2 .2 and its length is 2.7 kb, encoding a relative molecular mass of
