UniProt functional annotation for P01127

UniProt code: P01127.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Growth factor that plays an essential role in the regulation of embryonic development, cell proliferation, cell migration, survival and chemotaxis. Potent mitogen for cells of mesenchymal origin (PubMed:26599395). Required for normal proliferation and recruitment of pericytes and vascular smooth muscle cells in the central nervous system, skin, lung, heart and placenta. Required for normal blood vessel development, and for normal development of kidney glomeruli. Plays an important role in wound healing. Signaling is modulated by the formation of heterodimers with PDGFA (By similarity). {ECO:0000250|UniProtKB:P31240, ECO:0000269|PubMed:26599395}.
 
Subunit: Antiparallel homodimer; disulfide-linked. Antiparallel heterodimer with PDGFA; disulfide-linked. The PDGFB homodimer interacts with PDGFRA and PDGFRB homodimers, and with heterodimers formed by PDGFRA and PDGFRB. The heterodimer composed of PDGFA and PDGFB interacts with PDGFRB homodimers, and with heterodimers formed by PDGFRA and PDGFRB. Interacts with XLKD1 (By similarity). Interacts with LRP1 (PubMed:15053742). Interacts with SORL1 (via the N-terminal ectodomain) (PubMed:15053742, PubMed:16393139). {ECO:0000250, ECO:0000269|PubMed:15053742, ECO:0000269|PubMed:16393139}.
Subcellular location: Secreted. Note=Released by platelets upon wounding.
Tissue specificity: Expressed at high levels in the heart, brain (sustantia nigra), placenta and fetal kidney. Expressed at moderate levels in the brain (hippocampus), skeletal muscle, kidney and lung. {ECO:0000269|PubMed:11331882}.
Disease: Basal ganglia calcification, idiopathic, 5 (IBGC5) [MIM:615483]: A form of basal ganglia calcification, an autosomal dominant condition characterized by symmetric calcification in the basal ganglia and other brain regions. Affected individuals can either be asymptomatic or show a wide spectrum of neuropsychiatric symptoms, including parkinsonism, dystonia, tremor, ataxia, dementia, psychosis, seizures, and chronic headache. Serum levels of calcium, phosphate, alkaline phosphatase and parathyroid hormone are normal. The neuropathological hallmark of the disease is vascular and pericapillary calcification, mainly of calcium phosphate, in the affected brain areas. {ECO:0000269|PubMed:23913003, ECO:0000269|PubMed:26599395}. Note=The disease is caused by variants affecting the gene represented in this entry.
Disease: Note=A chromosomal aberration involving PDGFB is found in dermatofibrosarcoma protuberans. Translocation t(17;22)(q22;q13) with PDGFB. {ECO:0000269|PubMed:12660034}.
Pharmaceutical: Available under the name Regranex (Ortho-McNeil). Used to promote healing in diabetic neuropathic foot ulcers.
Similarity: Belongs to the PDGF/VEGF growth factor family. {ECO:0000305}.
