## Homologies in amino-acid sequence indicate that all known protein kinases share a conserved catalytic core, and, thus, belong to a relatedfamily ofproteins that have evolved in part from a common ancestoral origin. This family includes cellular kinases, oncogenic viral kinases and their protoonco

Abstract
A protein kinase cascade is involved in the action of some mitogens. The cascade begins with receptor tyrosine kinase activation by growth factors. The resulting signal is transmitted into cells via phospholipid metabolism which produces a variety of second messengers and by intracellular protein kinase activation. The signal is then propagated and disseminated via a network of other proteln kinases and protein phosphatases. Recent research suggests that ribosomal protein S6 kinase and casein kinase II are two important elements in the kinase cascade that leads to the initiation of growth. The nature and some properties of these hitherto lesser known enzymes is considered.

nases. These results suggest that PTK, Ras, and PKC Hepatocyte growth factor (HGF) stimulated mitogenplay roles in MAP kinase activation induced by HGF and activated protein (MAP) kinases and MAP kinase kinase that MAP kinase activation resulting in AA release is in primary cultured rat hepatocytes.
Syk, a nonreceptor type of protein tyrosine kinase widely expressed in hematopoietic cells, is a candidate suppressor gene in human breast cancer. Reduced expression of Syk protein is correlated with poor prognosis, while its overexpression can reduce the malignant phenotype of breast cancer cells.

## Abstract The present focus survey represents a short review of current knowledge concerning involvement of protein kinases in control of basic ovarian functions. Ovarian cells produce a number of protein kinases, whose expression depends on type of cells, their state and action of hormones and o
## Abstract Mitogenβactivated protein kinases (MAPKs) are evolutionary conserved enzymes which play a key role in signal transduction mediated by cytokines, growth factors, neurotransmitters and various types of environmental stresses. In the airways, these extracellular stimuli elicit complex infl
