      DescriptionAnti-IκB-α Antibody
      Background InformationThe NF-kappaB/Rel transcription factors are present in the cytosol in an inactive state, complexed with the inhibitory IkappaB-alpha protein. In response to many different NF-kappaB-inducing agentsincluding T-cell mitogens, proinflammatory cytokines, and viral transactivatorsthe inhibitory IkappaB-alpha is rapidly phosphorylated and degraded. Phosphorylation of IkappaB-alpha at Ser32 and Ser36 has been shown to stimulate conjugation with ubiquitin and subsequent degradation of IkappaB-alpha. Phosphorylation of IkappaB-alpha at Ser32 and Ser36 is critical for activation of NF-kappaB, which then translocates to the nucleus and induces transcription of genes that protect organism.

      Entrez Gene Number
      Entrez Gene SummaryNFKB1 (MIM 164011) or NFKB2 (MIM 164012) is bound to REL (MIM 164910), RELA (MIM 164014), or RELB (MIM 604758) to form the NFKB complex. The NFKB complex is inhibited by I-kappa-B proteins (NFKBIA or NFKBIB, MIM 604495), which inactivate NF-kappa-B by trapping it in the cytoplasm. Phosphorylation of serine residues on the I-kappa-B proteins by kinases (IKBKA, MIM 600664, or IKBKB, MIM 603258) marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF-kappa-B complex. Activated NFKB complex translocates into the nucleus and binds DNA at kappa-B-binding motifs such as 5-prime GGGRNNYYCC 3-prime or 5-prime HGGARNYYCC 3-prime (where H is A, C, or T; R is an A or G purine; and Y is a C or T pyrimidine).[supplied by OMIM]

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P25963 # Inhibits NF-kappa-B by complexing with and trapping it in the cytoplasm. May be involved in regulation of transcriptional responses to NF-kappa-B, including cell adhesion, immune and proinflammatory responses, apoptosis, differentiation and growth. Controlled by sequential serine-phosphorylation, ubiquitination and degradation. Tyrosine-phosphorylation could only lead to dissociation from NF-kappa-B.
      SIZE: 317 amino acids; 35609 Da
      SUBUNIT: Interacts with p65 (RELA). Interacts with NKIRAS1 and NKIRAS2. Interacts with HBV protein X.
      PTM: Phosphorylated; disables inhibition of NF-kappa-B DNA-binding activity. & Ubiquitinated; subsequent to stimulus-dependent phosphorylation on serines, polyubiquitination targets the protein for rapid degradation via the ubiquitin system.
      DISEASE: SwissProt: P25963 # Defects in NFKBIA are a cause of autosomal dominant anhidrotic ectodermal dysplasia with immunodeficiency (AD-EDA-ID) [MIM:164008]. Ectodermal dysplasias (EDs) constitute a heterogeneous group of developmental disorders affecting tissues of ectodermal origin. EDs are characterized by abnormal development of two or more ectodermal structures such as hair, teeth, nails and sweat glands, with or without any additional clinical sign. Each combination of clinical features represents a different type of ectodermal dysplasia.
      SIMILARITY: SwissProt: P25963 ## Belongs to the NF-kappa-B inhibitor family. & Contains 5 ANK repeats.
