MOS PROTO ONCOGENE Meaning and
Definition
-
The mos proto-oncogene is a gene that encodes a protein called the Mos protein kinase. It is derived from the transforming retrovirus of the Moloney murine sarcoma virus and is considered to be a homolog of the v-mos oncogene. The mos proto-oncogene is involved in regulating cell division and the progression from the G2 phase to the M phase of the cell cycle.
The protein encoded by the mos proto-oncogene functions as a serine/threonine kinase, which means it adds a phosphate group to specific target proteins. This phosphorylation process is essential for the proper progression of the cell cycle. The Mos protein kinase specifically targets and activates another protein kinase called MPF (maturation promoting factor), also known as Cyclin B-Cdk1 complex.
Activation of MPF by Mos protein kinase triggers the entry of cells into mitosis, the phase where chromosomes are divided and two daughter cells are formed. The Mos protein kinase is predominantly expressed in oocytes, the immature eggs, where it plays a critical role in meiotic cell divisions. It is also involved in regulating early embryonic development.
Aberrant activation or overexpression of the mos proto-oncogene can lead to uncontrolled cell growth and potential tumor formation. However, it should be noted that the mos proto-oncogene itself does not directly cause cancer, but rather its abnormal expression or activity can contribute to the development and progression of cancerous cells.
