该基因编码由血小板衍生生长因子(PDGF)和血管内皮生长因子(VEGF)组成的蛋白家族成员。编码的前蛋白经蛋白质水解处理产生血小板衍生生长因子B亚单位,该亚单位可与相关的血小板衍生生长因子A亚单位同二聚或异二聚。这些蛋白结合并激活pdgf受体酪氨酸激酶,在广泛的发育过程中发挥作用。该基因的突变与脑膜瘤有关。染色体22和17之间的相互易位,在这个基因和胶原1型α1的位置,与一种罕见的皮肤肿瘤——皮肤纤维肉瘤突起有关。选择性剪接导致多个转录变体。
This gene encodes a member of the protein family comprised of both platelet-derived growth factors (PDGF) and vascular endothelial growth factors (VEGF). The encoded preproprotein is proteolytically processed to generate platelet-derived growth factor subunit B, which can homodimerize, or alternatively, heterodimerize with the related platelet-derived growth factor subunit A. These proteins bind and activate PDGF receptor tyrosine kinases, which play a role in a wide range of developmental processes. Mutations in this gene are associated with meningioma. Reciprocal translocations between chromosomes 22 and 17, at sites where this gene and that for collagen type 1, alpha 1 are located, are associated with dermatofibrosarcoma protuberans, a rare skin tumor. Alternative splicing results in multiple transcript variants.
