FGFR1(成纤维细胞生长因子受体1)属于FGFR基因家族,该家族包括FGFR1、FGFR2、FGFR3和FGFR4四个成员,它们编码的蛋白质都是跨膜酪氨酸激酶受体,通过与成纤维细胞生长因子(FGFs)结合激活下游信号通路,调控细胞增殖、分化、迁移和存活等生物学过程。FGFR1在胚胎发育、血管生成、骨骼形成和神经系统发育中发挥关键作用。FGFR1蛋白由胞外配体结合域、跨膜区和胞内酪氨酸激酶域组成,主要通过与FGF配体结合后发生二聚化并自磷酸化,激活MAPK、PI3K-AKT和STAT等信号通路。FGFR1的突变可能导致其功能异常,例如激酶域的点突变(如N546K、K656E)会导致受体持续激活,与多种疾病相关,包括骨骼发育异常(如Pfeiffer综合征)、癌症(如乳腺癌、肺癌和白血病)以及内分泌疾病(如Kallmann综合征)。FGFR1过表达会促进细胞增殖和肿瘤发生,尤其在乳腺癌和胶质母细胞瘤中常见,可能导致治疗耐药性;而FGFR1表达降低则可能影响组织修复和血管生成,导致发育缺陷或伤口愈合延迟。FGFR1的异常表达还会影响其他基因,如上调MMP(基质金属蛋白酶)促进肿瘤转移,或干扰其他FGFR家族成员的功能。FGFR基因家族的共性在于它们均通过相似的机制传递FGF信号,但各成员在组织分布和功能上存在差异,例如FGFR1和FGFR2更多参与骨骼发育,而FGFR3与软骨发育密切相关。针对FGFR1的靶向药物(如厄达替尼)已用于治疗携带FGFR突变的癌症,但需注意耐药性和副作用问题。
The protein encoded by this gene is a member of the fibroblast growth factor receptor (FGFR) family, where amino acid sequence is highly conserved between members and throughout evolution. FGFR family members differ from one another in their ligand affinities and tissue distribution. A full-length representative protein consists of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of the protein interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. This particular family member binds both acidic and basic fibroblast growth factors and is involved in limb induction. Mutations in this gene have been associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, osteoglophonic dysplasia, and autosomal dominant Kallmann syndrome 2. Chromosomal aberrations involving this gene are associated with stem cell myeloproliferative disorder and stem cell leukemia lymphoma syndrome. Alternatively spliced variants which encode different protein isoforms have been described; however, not all variants have been fully characterized. [provided by RefSeq, Jul 2008]
