A mitogen-activated protein kinase (MAPK or MAP kinase) is a type of serine/threonine-specific protein kinases involved in directing cellular responses to a diverse array of stimuli, such as mitogens, osmotic stress, heat shock and proinflammatory cytokines.
Mitogen-activated protein kinase (MAPK) networks are the pathways and signaling of MAPK, which is a protein kinase that consists of amino acids serine and threonine. [1] MAPK pathways have both a positive and negative regulation in plants. A positive regulation of MAPK networks is to help in assisting with stresses from the environment.
Subsequently, MAP kinase kinase activates MAP kinase. Several types of MAPKKK can exist but are mainly characterized by the MAP kinases they activate. MAPKKKs are stimulated by a large range of stimuli, primarily environmental and intracellular stressors. MAPKKK is responsible for various cell functions such as cell proliferation, cell ...
Mitogen-activated protein kinase 3 (MAPK3) is also known as extracellular signal-regulated kinase 1 (ERK1). Transgenic gene knockout mice lacking MAPK3 are viable and it is thought that MAPK1 can fulfill some MAPK3 functions in most cells. [11] The main exception is in T cells. Mice lacking MAPK3 have reduced T cell development past the CD4 ...
MAP3K1 is highly conserved in Euteleostomi. [19] The spontaneous recessive lidgap-Gates mutation (deletion of Map3k1 exons 2–9, initially described in the 1960s) identified on the SELH/Bc mouse strain causes the same open-eyelids-at-birth mutational phenotype as the gene knockout mutations of the mouse (but not human) MAP3K1 homolog (Map3k1) and also co-maps to distal Chromosome 13.

Mitogen-activated protein kinase kinase (also known as MAP2K, MEK, MAPKK) is a dual-specificity kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK). MAP2K is classified as EC 2.7.12.2. There are seven genes: MAP2K1 (a.k.a. MEK1) MAP2K2 (a.k.a. MEK2) MAP2K3 (a.k.a. MKK3) MAP2K4 (a.k.a. MKK4) MAP2K5 (a.k.a. MKK5) MAP2K6 (a ...
The protein encoded by this gene is a member of the MAP kinase and JNK family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation , differentiation , transcription regulation and development.
