The mitogen-activated protein kinase (MAPK) pathway.[ 1] [ 2] [ 3] [ 4] [ 5] [ 6] [ 7] [ 8] [ 9] [ 10] RAF-1 is between RAS and MEK just above the centre of the diagram.
RAF kinases are a family of three serine/threonine-specific protein kinases that are related to retroviral oncogenes .[ 11] The mouse sarcoma virus 3611 contains a RAF kinase-related oncogene that enhances fibrosarcoma induction. RAF is an acronym for R apidly A ccelerated F ibrosarcoma.[ 12]
RAF kinases participate in the RAS -RAF-MEK -ERK signal transduction cascade, also referred to as the mitogen-activated protein kinase (MAPK) cascade .[ 11] Activation of RAF kinases requires interaction with RAS-GTPases .
The three RAF kinase family members are:
