摘要:
We have isolated two novel protein kinase genes, MHK and NAK, from the plant Arabidopsis thaliana by using low stringency hybridization with the catalytic domain of a putative plant receptor protein kinase. Sequence analysis of the cDNAs reveals that MHK is a member of the cdc2+ family of protein kinases and is particularly similar to the mak gene of rats; mak encodes a protein kinase that may play a role in spermatogenesis. NAK encodes a candidate protein kinase that is similar to the oncogenes met and abl. The homology that these two Arabidopsis genes share with other protein kinases suggests that they may play a role in the regulation of plant growth and development.
