NOTCH1-mediated pathway for NF-KB activity modulation
Interleukin 1 ( IL-1 ) activates Nuclear factor of kappa light polypeptide gene enhancer in B-cells ( NF-KB ) via Interleukin-1 receptor-associated kinase ( IRAK ) and Mitogen-activated protein kinase kinase kinase 1 ( MEKK1(MAP3K1) )-dependent inhibition of nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor ( I-kB ) , . V-rel reticuloendotheliosis viral oncogene homolog ( c-Rel (NF-kB subunit) ) can trigger Notch homolog 1 translocation-associated ( NOTCH1 receptor ) signaling pathway by inducing expression of Jagged1, ligand for Notch receptors , . NOTCH1 receptor activated by Jagged1 or Delta-like 1 ( DLL1 ) is cleaved by ADAM metallopeptidase domain 17 ( ADAM17 ) and Presenilin1 to intracellular domain of NOTCH1 ( NOTCH1 (NICD) ). NOTCH1 (NICD) is transported to nucleus and participates in recombination signal binding protein for immunoglobulin kappa J region ( RBP-J kappa (CBF1) )-mediated transcription , .
RBP-J kappa (CBF1) can act as transcription repressor or activator, depending on protein complex, which it recruits to DNA , , . RBP-J kappa (CBF1) acts as gene repressor in a complex with co-repressors Nuclear receptor co-repressor 2 ( SMRT )/Nuclear receptor co-repressor 1 ( N-CoR )/ Histone deacetylase 1 ( HDAC1 ) ,  or CBF1 interacting corepressor ( CIR )/ Sin3A-associated protein 30kDa ( SAP30 )/ Histone deacetylase 2 ( HDAC2 ) , . HDAC participates in histone deacetylation, which prevents transcription. SMRT and CIR function act as linkers between HDAC and RBP-J kappa (CBF1) via direct binding of linker protein SNW domain containing 1 ( SKIP ) , , , . Intracellular domain of Notch homolog 1 translocation-associated ( NOTCH1 (NICD) ) binding to SKIP competes with SMRT  and, possibly, CIR . NOTCH1 (NICD) recruits Mastermind-like 1 ( MAML1 ), which facilitates E1A binding protein p300 ( p300 ) recruitment. The latter in turn facilitates p300/CBP-associated factor ( PCAF ) recruitment. Complex MAML1/ p300/ PCAF acts as histone acetylase and assist chromatin remodeling. NOTCH1 (NICD) competition with RBP-J kappa (CBF1) corepressors determines positive regulation of transcription by NOTCH1 (NICD).
This pathway enables NOTCH1 (NICD) activation of transcription of Nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor alpha ( NFKBIA ) and thus lowers NF-KB activity .
