title: Cloning and characterization of H4 (D10S170), a gene involved in RET rearrangements in vivo.
abstract: H4(D10S170) is a gene which we isolated because of its frequent rearrangement with the RET proto-oncogene in vivo. Its fusion to RET generates the RET/PTC1 oncogene, which has been detected in about 20% of human thyroid papillary carcinomas. We have cloned and sequenced the cDNA corresponding to the H4(D10S170) gene from a human normal thyroid cDNA library. The nucleotide sequence of the H4(D10S170) 3 kb transcript shows no significant homology to known genes and contains an open reading frame (ORF) of 585 amino acids. H4(D10S170) predicted protein has no transmembrane domain and shows extensive regions in the alpha helical conformation, which are 30% homologous to the alpha-helical domains of several proteins including tropomyosin, vimentin, keratin and the tail region of myosin heavy chain. A putative SH3 binding site is present at the carboxy terminus, which suggests that H4(D10S170) might be a cytoskeletal protein.
