Oncoprotein protein kinase

摘要

An isolated polypeptide (JNK) characterized by having a molecular weight of 46 kD as determined by reducing SDS-PAGE, having serine and Threonine kinase activity, phosphorylating the c-Jun N-terminal activation domain and polynucleotide sequences and method of deterction of JNK are provided herein. JNK phosphorylates c-Jun N-terminal activation domain which affects gene expression from AP-1 sites.
