Rabbit anti-Human TAB3 Polyclonal Antibody

Uniprot Id

Q8N5C8

Target Species

Human

Target Name

TAB3

Target Full Name

TGF-beta-activated kinase 1 and MAP3K7-binding protein 3

Target Function

Adapter required to activate the JNK and NF-kappa-B signaling pathways through the specific recognition of 'Lys-63'-linked polyubiquitin chains by its RanBP2-type zinc finger (NZF). Acts as an adapter linking MAP3K7/TAK1 and TRAF6 to 'Lys-63'-linked polyubiquitin chains. The RanBP2-type zinc finger (NZF) specifically recognizes Lys-63'-linked polyubiquitin chains unanchored or anchored to the substrate proteins such as RIPK1/RIP1: this acts as a scaffold to organize a large signaling complex to promote autophosphorylation of MAP3K7/TAK1, and subsequent activation of I-kappa-B-kinase (IKK) core complex by MAP3K7/TAK1.; May be an oncogenic factor.

Target Tissue Specificity

Widely expressed. Constitutively overexpressed in certain tumor tissues.; [Isoform 1]: Major transcript.; [Isoform 2]: Minor transcript.

Target Synonyms

MAP3K7IP 3; Mitogen-activated protein kinase kinase kinase 7-interacting protein 3; NAP1 ; NF-kappa-B-activating protein 1; NFkB activating protein 1; TAB-3; Tab3; TAB3_HUMAN; TAK1 binding protein 3; TAK1-binding protein 3; TGF-beta-activated kinase 1 and MAP3K7-binding protein 3; TGF-beta-activated kinase 1-binding protein 3

Target Background

The product of this gene functions in the NF-kappaB signal transduction pathway. The encoded protein, and the similar and functionally redundant protein MAP3K7IP2/TAB2, forms a ternary complex with the protein kinase MAP3K7/TAK1 and either TRAF2 or TRAF6 in response to stimulation with the pro-inflammatory cytokines TNF or IL-1. Subsequent MAP3K7/TAK1 kinase activity triggers a signaling cascade leading to activation of the NF-kappaB transcription factor. The human genome contains a related pseudogene. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.
