Protein attributes
| Sequence length | 1062 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Suppresses TNF- and CD40-induced NFKB1 activity at the level of the IKK complex, by inhibiting NFKBIA degradation induced by TNF. When associated with PYCARD, activates CASP1, leading to the secretion of mature proinflammatory cytokine IL1B. May be a component of the inflammasome, a protein complex which also includes PYCARD, CARD8 and CASP1 and whose function would be the activation of proinflammatory caspases. Ref.9 |
| Subunit structure | Interacts with CHUK, IKBKB and IKBKG, as well as with full-length PYCARD and with the DAPIN domain of NAPL1, but not the full-length protein. Ref.8 Ref.9 |
| Subcellular location | |
| Tissue specificity | Expressed at high levels in lung, placenta and thymus and at lower levels in ovary, intestine and brain. Ref.9 |
| Induction | By interferons and bacterial lipopolysaccharides (LPS). Ref.9 |
| Domain | The DAPIN domain is necessary and sufficient for suppression of NFKB1 activation induced by TNF and for inducing IL1B secretion in collaboration with caspase-1. It is involved in interaction with PYCARD. When isolated, the NACHT domain is involved in interaction with CARD8. This interaction is not detected for the full-length protein, maybe due to autoinhibition, this inhibition might by relieved by an inducible change in protein folding. |
| Sequence similarities | Belongs to the NLRP family. Contains 1 DAPIN domain. Contains 8 LRR (leucine-rich) repeats. Contains 1 NACHT domain. |
| Sequence caution | The sequence AAG15253.1 differs from that shown. Reason: Erroneous initiation. The sequence BAA91377.1 differs from that shown. Reason: Erroneous initiation. The sequence BAD92537.1 differs from that shown. Reason: Frameshift at position 769. The sequence BAD92537.1 differs from that shown. Reason: Erroneous prediction of the initiator methionine. |

Alternative products
| This entry describes 5 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q9NX02-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q9NX02-2) The sequence of this isoform differs from the canonical sequence as follows: 133-154: Missing. | ||||||
| Isoform 3 (identifier: Q9NX02-3) The sequence of this isoform differs from the canonical sequence as follows: 847-1062: Missing. | ||||||
| Note: No experimental confirmation available. May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. | ||||||
| Isoform 4 (identifier: Q9NX02-4) The sequence of this isoform differs from the canonical sequence as follows: 109-132: Missing. | ||||||
| Note: No experimental confirmation available. | ||||||
| Isoform 5 (identifier: Q9NX02-5) The sequence of this isoform differs from the canonical sequence as follows: 47-69: Missing. | ||||||
| Note: No experimental confirmation available. |
