Descriptions
(Annotation based on sequence homology with Q16584)
Mixed lineage kinase 3 (MLK3) is a mitogen-activated protein kinase kinase kinase (MAPKKK) that activates the c-Jun N-terminal kinase (JNK) pathway through the dual phosphorylation of mitogen-activated protein kinase kinases 4/7 (MKK4/7). The catalytic domain of MLK3 is flanked by an N-terminal SH3 domain and a centrally located zipper and Cdc42/Rac-interactive binding (CRIB) motif. Zipper-mediated homo-oligomerization is required for full activity of MLK3, proper substrate phosphorylation, and activation of the JNK pathway. MLK3 is autoinhibited through an interaction between its SH3 domain and a proline-containing sequence between the zipper and the CRIB motif. Activated forms of the small GTPases Cdc42 and Rac interact with MLK3 in a CRIB motif-dependent manner to increase the autophosphorylation of MLK3 and substrate phosphorylation activity and to potentiate MLK3-induced activation of JNK. Activated Cdc42 translocates MLK3 to membranes and induces activation loop phosphorylation of MLK3.

3 GO annotations of cellular component
Name | Definition |
---|---|
centrosome | A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle. |
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
microtubule | Any of the long, generally straight, hollow tubes of internal diameter 12-15 nm and external diameter 24 nm found in a wide variety of eukaryotic cells; each consists (usually) of 13 protofilaments of polymeric tubulin, staggered in such a manner that the tubulin monomers are arranged in a helical pattern on the microtubular surface, and with the alpha/beta axes of the tubulin subunits parallel to the long axis of the tubule; exist in equilibrium with pool of tubulin monomers and can be rapidly assembled or disassembled in response to physiological stimuli; concerned with force generation, e.g. in the spindle. |

identical protein binding | Binding to an identical protein or proteins. |
JUN kinase kinase kinase activity | Catalysis of the reaction: JNKK + ATP = JNKK phosphate + ADP. This reaction is the phosphorylation and activation of JUN kinase kinases (JNKKs). |

mitogen-activated protein kinase kinase binding | Binding to a mitogen-activated protein kinase kinase, a protein that can phosphorylate a MAP kinase. |
mitogen-activated protein kinase kinase kinase binding | Binding to a mitogen-activated protein kinase kinase kinase, a protein that can phosphorylate a MAP kinase kinase. |
protein homodimerization activity | Binding to an identical protein to form a homodimer. |
protein serine kinase activity | Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate. |
protein serine/threonine kinase activity | Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate. |
small GTPase binding | Binding to a small monomeric GTPase. |
11 GO annotations of biological process
Name | Definition |
---|---|
cell cycle G1/S phase transition | The cell cycle process by which a cell in G1 phase commits to S phase. |
cell death | Any biological process that results in permanent cessation of all vital functions of a cell. A cell should be considered dead when any one of the following molecular or morphological criteria is met: (1) the cell has lost the integrity of its plasma membrane; (2) the cell, including its nucleus, has undergone complete fragmentation into discrete bodies (frequently referred to as apoptotic bodies). The cell corpse (or its fragments) may be engulfed by an adjacent cell in vivo, but engulfment of whole cells should not be considered a strict criteria to define cell death as, under some circumstances, live engulfed cells can be released from phagosomes (see PMID:18045538). |
JNK cascade | An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (a MAP3K). The cascade can also contain an additional tier: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell. |
MAPK cascade | An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell. |
microtubule-based process | Any cellular process that depends upon or alters the microtubule cytoskeleton, that part of the cytoskeleton comprising microtubules and their associated proteins. |
positive regulation of apoptotic process | Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process. |
positive regulation of JNK cascade | Any process that activates or increases the frequency, rate or extent of signal transduction mediated by the JNK cascade. |
positive regulation of JUN kinase activity | Any process that activates or increases the frequency, rate or extent of JUN kinase activity. |

protein autophosphorylation | The phosphorylation by a protein of one or more of its own amino acid residues (cis-autophosphorylation), or residues on an identical protein (trans-autophosphorylation). |
protein phosphorylation | The process of introducing a phosphate group on to a protein. |
