ERC2 Intronic Transcript Protein 1 (ERC2IT1)
The human chromosome 1p36 region displays frequent nonrandom chromosomal deletions and translocations in a number of human malignancies; these are thought to inactivate tumor suppressor genes. C1orf1, FRAP2, ENO1L1, and XBX1 appeared to be expressed ubiquitously in the tissues tested, with transcript sizes of 4.5, 8.7, 1.75, and 4.5 kb, respectively. Using fluorescence in situ hybridization, mapped the five novel genes relative to chromosome 1p36 breakpoints present in three established tumor cell lines and one nontumor cell line. The karyotypic abnormalities in these cell lines were exploited as chromosomal landmarks;the telomere to centromere gene order was PTPRZ2-(MBP-1/ENO1/ENO1L1)-(C1orf1/XBX1)-+ ++FRAP2. The localization of these genes to a chromosomal region that is prone to deletions in human cancers makes them potential candidate tumor suppressors.
