摘要：

In plants, protein kinase CK2 is involved in different processes that control many aspects of metabolism and development. In mammals and yeast the enzyme is a heterotretamer composed of two types of subunits. During years the subunit composition of the maize protein kinase CK2 enzyme has been a source of controversy. We have recently characterized the maize holoenzyme subunits. Our results show that multiple catalytic and regulatory subunits are expressed in maize and are able to specifically interact with other alpha and beta subunits suggesting a high level of heterogeneity in the typical heterotetrameric structure. Here, we summarize data available on plant CK2 enzymes, in order to clarify the distinctive features and functions of plant protein kinase CK2.
