RelA

NFkB and p62 Both Activate and Regulate Inflammation

Nuclear factor kappa-light-chain-enhancer of activated B cells (NFkB) is a protein complex that regulates DNA transcription and is a critical regulator of cell survival. NFkB has long been known as a primer of inflammation, however researchers are now finding that NFkB may also regulate over-inflammation via a novel mitophagy pathway (Minton, 2016).

The subunit RelA(p65) mediates NF-kB signal transduction in multiple ways

RelA (also known as p65) is an NF-kB family member and a subunit of the NF-kB transcription factor complex.  The mammalian NF-kB family has five members (NF-kB1, NF-kB2, RelA (p65), RelB, and c-Rel), each of which contains an N-terminal Rel homology domain. Active NF-kB protein complexes are dimeric (hetero- or homo-), and are made up of two family members. NF-kB signaling is activated in response to many different types of stimuli and modulates transcription of numerous downstream targets.
