MKP5とは 意味・読み方・使い方

MKP5 is a member of DS-MKP family . Its structural features include the presence of an N-terminus (NT) domain of unknown function in addition to the MKB and DSP domains that are characteristic of other members of DS-MKP family. MKP5 shows preference for dephosphorylating JNK and p38 MAPKs but not ERK. It has been hypothesized that the novel NT domain is possibly a protein interaction domain that may be involved in interaction with other cellular proteins and thereby providing a mechanism for cross-talk between MAPK and other signaling pathways involved in regulating cellular functions. The NT domain thus suggests another element of complexity in the biological function of DS-MKPs.
