[[http://www.uniprot.org/uniprot/SO2A1_HUMAN SO2A1_HUMAN]] Defects in SLCO2A1 are the cause of hypertrophic osteoarthropathy, primary, autosomal recessive, type 2 (PHOAR2) [MIM:[http://omim.org/entry/614441 614441]]. PHOAR2 is a disease characterized by digital clubbing, periostosis, acroosteolysis, painful joint enlargement, and variable features of pachydermia that include thickened facial skin and a thickened scalp. Other developmental anomalies include delayed closure of the cranial sutures and congenital heart disease.<ref>PMID:22331663</ref><ref>PMID:22197487</ref><ref>PMID:22553128</ref><ref>PMID:22696055</ref> [[http://www.uniprot.org/uniprot/B2MG_HUMAN B2MG_HUMAN]] Defects in B2M are the cause of hypercatabolic hypoproteinemia (HYCATHYP) [MIM:[http://omim.org/entry/241600 241600]]. Affected individuals show marked reduction in serum concentrations of immunoglobulin and albumin, probably due to rapid degradation.<ref>PMID:16549777</ref> Note=Beta-2-microglobulin may adopt the fibrillar configuration of amyloid in certain pathologic states. The capacity to assemble into amyloid fibrils is concentration dependent. Persistently high beta(2)-microglobulin serum levels lead to amyloidosis in patients on long-term hemodialysis.<ref>PMID:3532124</ref><ref>PMID:1336137</ref><ref>PMID:7554280</ref><ref>PMID:4586824</ref><ref>PMID:8084451</ref><ref>PMID:12119416</ref><ref>PMID:12796775</ref><ref>PMID:16901902</ref><ref>PMID:16491088</ref><ref>PMID:17646174</ref><ref>PMID:18835253</ref><ref>PMID:18395224</ref><ref>PMID:19284997</ref> | |||
==Function== | |||
[[http://www.uniprot.org/uniprot/1A02_HUMAN 1A02_HUMAN]] Involved in the presentation of foreign antigens to the immune system. [[http://www.uniprot.org/uniprot/SO2A1_HUMAN SO2A1_HUMAN]] May mediate the release of newly synthesized prostaglandins from cells, the transepithelial transport of prostaglandins, and the clearance of prostaglandins from the circulation. Transports PGD2, as well as PGE1, PGE2 and PGF2A. [[http://www.uniprot.org/uniprot/B2MG_HUMAN B2MG_HUMAN]] Component of the class I major histocompatibility complex (MHC). Involved in the presentation of peptide antigens to the immune system. | |||
