Mitogen-activated protein kinase 1 (MAPK1)

Serine/threonine kinase which acts as an important part of the MAP kinase signal transduction pathway. MAPK1/ERK2 and MAPK3/ERK1 will be the 2 MAPKs which play an significant role in the MAPK/ERK cascade.

They participate also in a signaling cascade initiated by activated KIT and KITLG/SCF. Based on the cellular context, the MAPK/ERK cascade mediates diverse biological functions such as cell growth, adhesion, survival and differentiation through the regulation of transcription, translation, cytoskeletal rearrangements.
