Summary

PMID 18487086

[Homo sapiens] PYCARD protein contains CARD and Pyrin domains and is required for assembly of inflammasome.

PMID 14634131

[Homo sapiens] PYCARD prevents oligomerization of CASP1 mediated by RIPK2 by out-competing RIPK2 for binding, and thus, preventing CASP1 autoactivation. PYCARD also recruits CASP1 into PYCARD-formed cytosolic specks, separating it from RIPK2.

PMID 16585594

[Homo sapiens] PYCARD directs CASP1 away from RIPK2-mediated NF-kappaB activation, toward CASP1-mediated processing of pro-IL1B by interfering with CASP1-RIPK2 interaction.

PMID 19158675

[Homo sapiens] PYCARD binds to AIM2 to form a CASP1 and NF-kappaB activating inflammasome.

PMID 19759850

[Homo sapiens] PYCARD (ASC) splice variant protein (vASC) lacking the PGR domain regulates IL1B release and aggregates differently from intact PYCARD.

PMID 21439959

[Homo sapiens] PYCARD is a component of the inflammasome and is required for inflammation in acute pancreatitis. (Demonstrated in murine model)

PMID 22295065

[Homo sapiens] NLRP3/PYCARD inflammasome activation following human respiratory syncytial virus infection is dependent on the activation of TLR2/MYD88/NF-kB and reactive oxygen species/potassium efflux.

PMID 21439959

[Mus musculus] Pycard is a component of the inflammasome and is required for inflammation in acute pancreatitis.

PMID 22295065

[Mus musculus] Nlrp3/Pycard inflammasome activation following human respiratory syncytial virus infection is dependent on the activation of Tlr2/Myd88/NF-kB and reactive oxygen species/potassium efflux. (Demonstrated in human)

PMID 23302887

[Mus musculus] PYCARD is an essential regulator of inflammatory responses in West Nile virus encephalitis.

PMID 24185614

[Mus musculus] Phosphorylation of the inflammasome adaptor Pycard (ASC) controls inflammasome activity through the formation of ASC specks. The NLRP3 and AIM2 inflammasomes require Syk and Mapk8 (JNK) for their full activity .

PMID 25689249

[Mus musculus] Activation of the Nlrp3 inflammasome is detrimental during leishmaniasis. Mice lacking the inflammasome components Nlrp3, Pycard, Casp1 exhibit defective Il1b and Il18 production at the infection site and are resistant to cutaneous Leishmania major infection.

PMID 26071556

[Mus musculus] Mice lacking Pycard display attenuated pulmonary hypertension and right ventricle remodelling in response to hypoxia and this is accompanied by blunted inflammasome activation.

Entrez Gene

Summary

This gene does not have any Entrez summary - the following is the summary from its human ortholog ENSG00000103490:
This gene encodes an adaptor protein that is composed of two protein-protein interaction domains: a N-terminal PYRIN-PAAD-DAPIN domain (PYD) and a C-terminal caspase-recruitment domain (CARD). The PYD and CARD domains are members of the six-helix bundle death domain-fold superfamily that mediates assembly of large signaling complexes in the inflammatory and apoptotic signaling pathways via the activation of caspase. In normal cells, this protein is localized to the cytoplasm; however, in cells undergoing apoptosis, it forms ball-like aggregates near the nuclear periphery. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]
