Rabbit Anti-TNIP1/FITC Conjugated antibody
background:
Abin-1 is a 636 amino acid protein that localizes to both the nucleus and the cytoplasm and is shuttled between the two intercellular regions in a CRM1-dependent manner. Expressed ubiquitously with highest expression in spleen and skeletal muscle, Abin-1 interacts with A20 and, via this interaction, interferes with TRAF2-mediated transactivation signals and effectively inhibits TNF-induced NFⅹB expression. Additionally, Abin-1 can be incorporated into HISLV1 virions and, if overexpressed, can inhibit viral replication. Abin-1 may also play an important role in the regulation of nuclear import and export activities. Multiple isoforms of Abin-1 exist due to alternative splicing events.
Function:
Interacts with zinc finger protein A20/TNFAIP3 and inhibits TNF-induced NF-kappa-B-dependent gene expression by interfering with an RIP- or TRAF2-mediated transactivation signal (By similarity). Increases cell surface CD4(T4) antigen expression. Interacts with HISLV1 matrix protein and is packaged into virions and overexpression can inhibit viral replication. May regulate matrix nuclear localization, both nuclear import of PIC (Preintegration complex) and export of GAG polyprotein and viral genomic RNA during virion production.
Subunit:
Interacts with TNFAIP3 and IKBKG; facilitates TNFAIP3-mediated de-ubiquitination of NEMO/IKBKG. Interacts with HISLV1 matrix protein. Interacts with Shigella flexneri ipah9.8; the interaction promotes polyubiquitination of IKBKG. Interacts with polyubiquitin. Interacts with MAPK1, SELPLG and PIK3CD. Interacts with IKBKG (polyubiquitinated). Interacts with IRAK1 (polyubiquitinated). Interacts with MYD88; the interaction is indicative for participation in an activated TLR-signaling complex
Subcellular Location:
Cytoplasm. Nucleus. Note=Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner.
Tissue Specificity:
Ubiquitous. Strongly expressed in peripheral blood lymphocytes, spleen and skeletal muscle, and is weakly expressed in the brain.
Post-translational modifications:
Phosphorylation at Tyr-552 by SRSLCfamily kinases recruits phosphoinositide-3-kinase (PI3K) PIK3CD:p85 heterodimer which results in integrin activation and leukocyte adhesion to activated endothelium during inflammation.
Similarity:
Cytoplasm. Nucleus. Shuttles between the nucleus and cytoplasm in a CRM1-dependent manner.
