CYLD Antibody - #DF12193

Deubiquitinase that specifically cleaves 'Lys-63'- and linear 'Met-1'-linked polyubiquitin chains and is involved in NF-kappa-B activation and TNF-alpha-induced necroptosis. Plays an important role in the regulation of pathways leading to NF-kappa-B activation. Contributes to the regulation of cell survival, proliferation and differentiation via its effects on NF-kappa-B activation. Negative regulator of Wnt signaling. Inhibits HDAC6 and thereby promotes acetylation of alpha-tubulin and stabilization of microtubules. Plays a role in the regulation of microtubule dynamics, and thereby contributes to the regulation of cell proliferation, cell polarization, cell migration, and angiogenesis. Required for normal cell cycle progress and normal cytokinesis. Inhibits nuclear translocation of NF-kappa-B. Plays a role in the regulation of inflammation and the innate immune response, via its effects on NF-kappa-B activation. Dispensable for the maturation of intrathymic natural killer cells, but required for the continued survival of immature natural killer cells (By similarity). Negatively regulates TNFRSF11A signaling and osteoclastogenesis (By similarity). Involved in the regulation of ciliogenesis, allowing ciliary basal bodies to migrate and dock to the plasma membrane; this process does not depend on NF-kappa-B activation (By similarity). Ability to remove linear ('Met-1'-linked) polyubiquitin chains regulates innate immunity and TNF-alpha-induced necroptosis: recruited to the LUBAC complex via interaction with SPATA2 and restricts linear polyubiquitin formation on target proteins. Regulates innate immunity by restricting linear polyubiquitin formation on RIPK2 in response to NOD2 stimulation. Involved in TNF-alpha-induced necroptosis by removing linear ('Met-1'-linked) polyubiquitin chains from RIPK1, thereby regulating the kinase activity of RIPK1 (By similarity). Removes 'Lys-63' linked polyubiquitin chain of MAP3K7, which inhibits phosphorylation and blocks downstream activation of the JNK-p38 kinase cascades.

Ubiquitinated. Polyubiquitinated in hepatocytes treated with palmitic acid. Ubiquitination is mediated by E3 ligase TRIM47 and leads to proteasomal degradation.

Phosphorylated on several serine residues by IKKA and/or IKKB in response to immune stimuli. Phosphorylation requires IKBKG. Phosphorylation abolishes TRAF2 deubiquitination, interferes with the activation of Jun kinases, and strongly reduces CD40-dependent gene activation by NF-kappa-B.

Cytoplasm. Cytoplasm>Perinuclear region. Cytoplasm>Cytoskeleton. Cell membrane>Peripheral membrane protein>Cytoplasmic side. Cytoplasm>Cytoskeleton>Microtubule organizing center>Centrosome. Cytoplasm>Cytoskeleton>Spindle. Cytoplasm>Cytoskeleton>Cilium basal body.
Note: Detected at the microtubule cytoskeleton during interphase. Detected at the midbody during telophase. During metaphase, it remains localized to the centrosome but is also present along the spindle (PubMed:25134987).

Detected in fetal brain, testis, and skeletal muscle, and at a lower level in adult brain, leukocytes, liver, heart, kidney, spleen, ovary and lung. Isoform 2 is found in all tissues except kidney.

Interacts (via CAP-Gly domain) with IKBKG/NEMO (via proline-rich C-terminal region). Interacts with TRAF2 and TRIP. Interacts with PLK1, DVL1, DVL3, MAVS, TBK1, IKKE and DDX58. Interacts (via CAP-Gly domain) with microtubules. Interacts with HDAC6 and BCL3. Interacts with MAP3K7 (By similarity). Identified in a complex with TRAF6 and SQSTM1 (By similarity). Interacts with CEP350. Interacts with RNF31; the interaction is indirect and is mediated via SPATA2. Interacts with SPATA2 (via the PUB domain); the interaction is direct and recruits CYLD to the LUBAC complex, thereby regulating TNF-alpha-induced necroptosis.

Belongs to the peptidase C19 family.
