The gene HCAP1 (HCC-associated Protein 1), one variant of GEMIN4, has been mapped in a minimum LOH region on chromosome 17p13.3 and encodes a 1047-amino acid protein. Function predictions based on the amino acid sequence of protein HCAP1 revealed it to contain one helix-loop-helix motif and one leucine zipper domain. Using yeast two-hybrid screening, five zinc-finger proteins were identified as HCAP1-interacting proteins. Among them, NDP52 (nuclear dot protein 52) appeared most frequently in positive clones and was the most strongly interacting protein. Then, the interaction between HCAP1 and NDP52 was confirmed by GST pull-down assay and a coimmunoprecipitation experiment. Moreover, an immunofluorescent staining assay indicated that NDP52 colocalizes with HCAP1 in the cytoplasm. By deletion analysis, the leucine zipper domain of HCAP1 and the zinc finger domain of NDP52 were identified as important regions responsible for the interaction.

HCAP1 is a novel hepatic cancer related gene located on human chromosome 17p13.3. The loss of heterozygosity occurred at 17p13.3 in various human cancers. In order to investigate the effects of exogenous HCAP1 gene products on cell proliferation of T lymphoma Jurkat cell line, HCAP1 gene! was transfected into Jurkat cells mediated by liposome, and the cells stably expressing exogenous HCAP1 were screened with G418. The effects of HCAP1 products on cell proliferation were assessed by viable cell count, cell growth curve and colony formation assay in soft agar. The results showed that the HCAP1 transgenic Jurkat cells displayed slow growth rate, extended doubling time and reduced colony formation capability, as compared with the cells transfected with pBK/CMV empty vector (P < 0.01). It is concluded that exogenous HCAP1 gene products could inhibit the proliferation of Jurkat cells.
