KITLG(也称为干细胞因子SCF或steel因子)是一种重要的细胞因子,属于I型细胞因子家族。它通过结合其受体c-KIT(CD117)发挥作用,主要参与造血干细胞、黑色素细胞和生殖细胞的增殖、存活和分化。KITLG在骨髓、皮肤和睾丸等组织中高表达,对维持造血系统的稳态和黑色素生成至关重要。KITLG基因突变可能导致功能丧失,引发严重的遗传性疾病,如白化病(由于黑色素细胞发育缺陷)或骨髓造血功能障碍。KITLG过表达与某些癌症(如胃肠道间质瘤和急性髓系白血病)的发生相关,因为它可能过度激活c-KIT信号通路,促进细胞异常增殖。相反,KITLG表达降低可能导致造血功能受损或皮肤色素异常。KITLG属于KIT配体家族,该家族成员通常通过酪氨酸激酶受体发挥作用,调控细胞生长和分化。KITLG与c-KIT的相互作用还影响肥大细胞和生殖细胞的发育,其信号通路涉及PI3K/AKT和MAPK等关键途径。在临床应用中,重组KITLG被用于促进造血干细胞移植后的骨髓恢复。此外,KITLG的多态性与某些人群的皮肤和头发颜色变异有关,显示了其在人类表型多样性中的作用。

This gene encodes the ligand of the tyrosine-kinase receptor encoded by the KIT locus. This ligand is a pleiotropic factor that acts in utero in germ cell and neural cell development, and hematopoiesis, all believed to reflect a role in cell migration. In adults, it functions pleiotropically, while mostly noted for its continued requirement in hematopoiesis. Two transcript variants encoding different isoforms have been found for this gene.

该基因编码由KIT轨迹编码的酪氨酸激酶受体的配体。这种配位体是,在生殖细胞和神经细胞的发育,和造血宫内充当一种多效因子,所有认为反映在细胞迁移的作用。在成人中,它的功能pleiotropically,而主要是其在造血继续要求注意。已发现该基因编码不同亚型的两个转录变异体。 [由RefSeq的,2008年7月提供]
