title: [Chromosomal localization and inhibitory effect on TPK activition of a human novel gene hbrp].
abstract: The purpose of present study is to determine the location of the novel gene hbrp which is related to bovine seminal plasma (BSP) proteins in the human chromosome by the FISH (fluorescent in situ hybridization) technique, and to investigate the relation of HBRP to TPK( tyrosine protein kinase)by genetic engineering. The result is that the novel gene hbrp was successfully localized on human chromosome 19q1.3; HBRP protein obviously inhibited the activity of PKC. It is concluded that the structure of BSP contained two tandemly arranged fibronectin type II(Fn2)--domains which were related to the function of binding protein BSP. Amino acid sequence of HBRP protein with four tandemly arranged Fn2-domains showed that the protein might be binding protein functionly relating to BSP protein. We have concluded that HBRP protein obviously inhibited the activity of TPK. The location of the novel gene on human chromosome 19q1.3 is very important to study the other biological functions of the protein encoded by gene hbrp.
