The encoded protein is used as a determinant of lymphocyte differentiation. Defects in this gene can lead to the calcification of joints and arteries. Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2011]","ncbiEntrezGeneId":4907,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/4907","proteins":[{"symbol":"5NTD_HUMAN","href":"/api/1.0/protein/5NTD_HUMAN"}],"hgncRootFamilies":[{"name":"CD molecules (CD)","href":"/api/1.0/gene_family/CD+molecules+%28CD%29"}]}
