Abstract
We previously reported the presence of a new gene (HSET) with an unknown function, in the centromeric side of the class II gene region of the human major histocompatibility complex (MHC). cDNA clones corresponding to the HSET gene were isolated from a human testis cDNA library. A 2.4 kilobase transcript from the HSET gene was abundantly expressed in testis, B-cell, T-cell, and ovary cell lines but was not detected in lung or stomach. Analysis of the nucleotide sequence of the HSET cDNA clones revealed significant similarity to kinesin-related proteins in yeast, Drosophila, and human. Its predicted amino acid sequence contains a domain with strong sequence similarity to the ATP-binding and motor domains of a plus end-directed microtubule motor protein, kinesin, which might be involved in mitotic chromosome segregation, suggesting that the HSET gene encodes a novel kinesin-related protein.
