AHP1044 recognises the acetylated N-terminal of 14-3-3 beta. It is a member of the 14-3-3 family which consists of 30 kDa proteins that are involved in multiple protein kinase signalling pathways, regulation of cell cycle progression, cytoskeletal structure, transcription, intracellular trafficking and targeting. Protein interactions with 14-3-3 show distinct preference for it’s different isoforms and are regulated by phosphorylation of both 14-3-3 and the bound protein. 14-3-3 beta plays a role in the pathogenesis of systemic lupus erythematosus and is involved in negative regulation of p90 ribosomal S6 kinase activity and tuberous sclerosis tumour suppressor proteins. It also binds IGF-1 receptor, RAF1 and CDC25 phosphatases. AHP1044 may not react with recombinant proteins that are not N-acetylated.
