研究背景

P29466_CASP1_HUMAN

機能:

Thiol protease that cleaves IL-1 beta between an Asp and an Ala, releasing the mature cytokine which is involved in a variety of inflammatory processes. Important for defense against pathogens. Cleaves and activates sterol regulatory element binding proteins (SREBPs). Can also promote apoptosis. Upon inflammasome activation, during DNA virus infection but not RNA virus challenge, controls antiviral immunity through the cleavage of CGAS, rendering it inactive. In apoptotic cells, cleaves SPHK2 which is released from cells and remains enzymatically active extracellularly.

PTMs:

The two subunits are derived from the precursor sequence by an autocatalytic mechanism.

細胞の位置付け:

Cytoplasm. Cell membrane.

組織特異性:

サブユニット構造:

Heterotetramer that consists of two anti-parallel arranged heterodimers, each one formed by a 20 kDa (p20) and a 10 kDa (p10) subunit. The p20 subunit can also form a heterodimer with the epsilon isoform which then has an inhibitory effect. May be a component of the inflammasome, a protein complex which also includes PYCARD, CARD8 and NALP2 and whose function would be the activation of proinflammatory caspases. Both the p10 and p20 subunits interact with MEFV. Interacts with CARD17/INCA and CARD18. Interacts with SERPINB1; this interaction regulates CASP1 activity.

タンパク質ファミリー:

Belongs to the peptidase C14A family.
