FYN是一种属于SRC家族的非受体型酪氨酸激酶基因,在细胞信号传导中发挥重要作用。该基因编码的Fyn蛋白广泛分布于多种组织中,尤其在神经系统和免疫系统中表达丰富。Fyn蛋白通过其SH2和SH3结构域与其他蛋白质相互作用,参与调控T细胞受体信号通路、神经元发育、突触可塑性以及细胞黏附等关键生物学过程。在免疫系统中,Fyn与Lck协同作用,参与T细胞激活的早期信号事件。在神经系统中,Fyn通过调节NMDA受体和髓鞘形成影响学习记忆功能。FYN基因突变可能导致多种疾病,包括神经系统疾病如阿尔茨海默病(通过影响tau蛋白磷酸化)和免疫系统异常。FYN过表达与某些癌症如乳腺癌和前列腺癌的进展相关,可能促进肿瘤细胞迁移和侵袭;而表达降低则可能损害T细胞功能导致免疫缺陷。FYN属于SRC基因家族,该家族成员均含有SH2、SH3结构域和激酶结构域,通过酪氨酸磷酸化参与细胞信号转导,在细胞生长、分化、存活和运动等过程中起调控作用。SRC家族激酶通常通过与细胞膜受体结合而被激活,其活性异常与多种癌症发生密切相关。
该基??因是蛋白质 - 酪氨酸激酶致癌基因家族的一个成员。它编码已在细胞生长的控制被牵连的膜相关的酪氨酸激酶。与磷脂酰肌醇3激酶的P85亚基蛋白联营公司及与菲英岛结合蛋白相互作用。存在选择性剪接转录变异体的编码不同的亚型。 [由RefSeq的,2008年7月提供]
