Mixed lineage kinase domain like pseudokinase (MLKL) is a protein that in humans is encoded by the MLKL gene. [5]

Contents

Function

This gene belongs to the protein kinase superfamily. The encoded protein contains a protein kinase-like domain; however, is thought to be inactive because it lacks several residues required for activity. This protein plays a critical role in tumor necrosis factor (TNF)-induced necroptosis, a programmed cell death process, via interaction with receptor-interacting protein 3 (RIP3), which is a key signaling molecule in necroptosis pathway. Inhibitor studies and knockdown of this gene inhibited TNF-induced necrosis.

Influence in diseases

High levels of this protein and RIP3 are associated with inflammatory bowel disease in children. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Sep 2015]. A unique neurodegenerative disease has been reported in association with a homozygous frameshift mutation, rs561839347, in MLKL that causes replacement of part of the C-terminal pseudokinase domain with a 21-residue sequence of random amino acids.

Death receptor 6 (DR6), also known as tumor necrosis factor receptor superfamily member 21 (TNFRSF21), is a cell surface receptor of the tumor necrosis factor receptor superfamily which activates the JNK and NF-κB pathways. It is mostly expressed in the thymus, spleen and white blood cells. The Gene for DR6 is 78,450 bases long and is found on the 6th chromosome. This is transcribed into a 655 amino acid chain weighing 71.8 kDa. Post transcriptional modifications of this protein include glycosylation on the asparagines at the 82, 141, 252, 257, 278, and 289 amino acid locations.

<span class="mw-page-title-main">Necroptosis</span> Programmed form of necrosis, or inflammatory cell death

Necroptosis is a programmed form of necrosis, or inflammatory cell death. Conventionally, necrosis is associated with unprogrammed cell death resulting from cellular damage or infiltration by pathogens, in contrast to orderly, programmed cell death via apoptosis. The discovery of necroptosis showed that cells can execute necrosis in a programmed fashion and that apoptosis is not always the preferred form of cell death. Furthermore, the immunogenic nature of necroptosis favors its participation in certain circumstances, such as aiding in defence against pathogens by the immune system. Necroptosis is well defined as a viral defense mechanism, allowing the cell to undergo "cellular suicide" in a caspase-independent fashion in the presence of viral caspase inhibitors to restrict virus replication. In addition to being a response to disease, necroptosis has also been characterized as a component of inflammatory diseases such as Crohn's disease, pancreatitis, and myocardial infarction.

Immunogenic cell death is any type of cell death eliciting an immune response. Both accidental cell death and regulated cell death can result in immune response. Immunogenic cell death contrasts to forms of cell death that do not elicit any response or even mediate immune tolerance.

PANoptosis is a unique, innate immune, inflammatory, and lytic cell death pathway driven by caspases and RIPKs and regulated by multiprotein PANoptosome complexes. The assembly of the PANoptosome cell death complex occurs in response to germline-encoded pattern-recognition receptors (PRRs) sensing pathogens, including bacterial, viral, and fungal infections, as well as pathogen-associated molecular patterns, damage-associated molecular patterns, and cytokines that are released during infections, inflammatory conditions, and cancer. Several PANoptosome complexes, such as the ZBP1-, AIM2-, RIPK1-, and NLRP12-PANoptosomes, have been characterized so far.
