Mitogen Activated Protein (MAP) kinase kinase kinase (MAPKKK, [1] MKKK, [2] M3K, [3] or, MAP3K [4]) is a serine/threonine-specific protein kinase which acts upon MAP kinase kinase. Subsequently, MAP kinase kinase activates MAP kinase. Several types of MAPKKK can exist but are mainly characterized by the MAP kinases they activate.

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 kinase (also known as MAP2K, MEK, MAPKK) is a dual-specificity kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK). ...
Mitogen-activated protein kinase kinase kinase 4 is an enzyme that in humans is encoded by the MAP3K4 gene. [5] [6]The central core of each mitogen-activated protein kinase (MAPK) pathway is a conserved cascade of 3 protein kinases: an activated MAPK kinase kinase (MAPKKK) phosphorylates and activates a specific MAPK kinase (MAPKK), which then activates a specific MAPK.
The signal that starts the MAPK/ERK pathway is the binding of extracellular mitogen to a cell surface receptor.This allows a Ras protein (a Small GTPase) to swap a GDP molecule for a GTP molecule, flipping the "on/off switch" of the pathway.
Mank is a 2020 American biographical drama film about screenwriter Herman J. Mankiewicz and his development of the screenplay for the 1941 film Citizen Kane.It was directed by David Fincher based on a screenplay written by his late father Jack Fincher and was produced by Ceán Chaffin, Douglas Urbanski, and Eric Roth.
The animated film is set in two worlds: one enchanted and one human. The main theme of the film is a love story between an enchanted forest dweller and a human (Lukas), and their battle with the villain Kylina, who desires to own a magical forest wellspring. [13] Mavka: The Forest Song was released in Ukraine on March 2, 2023. [14]
