MCPIP1/ZC3H12A Antibody Blocking Peptide

Monocyte chemoattractant protein-induced protein 1 (MCPIP1), also referred to as ZC3H12A and Regnase-1, is an endonuclease that cleaves and destabilizes mRNA and functions as a negative regulator of inflammation (1,2). MCPIP1 is encoded by the ZC3H12A gene as a protein of 599 amino acids (aa) in length with a theoretical molecular weight of approximately 66 kDa (3-5). Common structural features of the MCPIP1 protein are the ubiquitin-associated (UBA) domain (43-89 aa), two protein-rich regions (PRRs) (100-126 aa, 458-536 aa), the PilT N-terminal (PIN) domain (133-270 aa), the zinc-finger motif (305-325 aa), the natively disordered region (326-457 aa), and the C-terminal conserved region (CCR) (545-598 aa) (1,3-5). MCPIP1 functions as an anti-inflammatory protein with RNase activity that is known to degrade many cytokine mRNA transcripts including interleukin-1beta (IL-1beta), IL-6, and IL-17 (4,5). In addition to its regulation of inflammation through mRNA degradation, MCPIP1 also controls inflammation through ubiquitin-specific peptidase 10 (USP10)-mediated protein deubiquitination of TRAF6 which results in suppression of c-Jun N-terminal kinase (JNK) and nuclear factor kappa B (NFkappaB) transcription factors (1,2,5). Besides regulating inflammation, MCPIP1 is involved in several non-immune cellular processes including apoptosis, adipogenesis, angiogenesis, and proliferation (2,5). MCPIP1 has also been implicated in a number of autoimmune diseases and other pathologies including chronic obstructive pulmonary disease (COPD), diabetes, rheumatoid arthritis, and cancer (3,5). Additionally, MCPIP1/ZC3H12A has been shown to have anti-viral activity against RNA viruses such as Japanese encephalitis virus and human immunodeficiency virus (HIV)-1 (1,5).
