PTTG1IP, Official Symbol PTTG1IPprovided by HGNC Official Full Name PTTG1 interacting proteinprovided by HGNC Primary source HGNC:HGNC:13524 See related Ensembl:ENSG00000183255 MIM:603784; AllianceGenome:HGNC:13524 Gene type protein coding RefSeq status REVIEWED Organism Homo sapiens Lineage Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo Also known as PBF; C21orf1; C21orf3; PTTG1IP1 Summary This gene encodes a single-pass type I integral membrane protein, which binds to pituitary tumor-transforming 1 protein (PTTG1), and facilitates translocation of PTTG1 into the nucleus. Coexpression of this protein and PTTG1 induces transcriptional activation of basic fibroblast growth factor. Alternatively spliced transcript variants have been found for this gene.
