SLU7 (N-acetyl-Ser2) Recombinant Rabbit mAb (S-3662-17)

SLU7 (N-acetyl-Ser2) protein refers to a specific post-translationally modified form of the SLU7 protein, a highly conserved splicing factor essential for the second catalytic step of pre-mRNA splicing in eukaryotes, where the designation "N-acetyl-Ser2" indicates that the serine residue at the second position of its N-terminus has undergone N-terminal acetylation, a common co-translational modification catalyzed by NatA complexes that often influences protein stability, subcellular localization, or interaction with other components of the spliceosome; while the core function of SLU7 involves stabilizing the active site conformation and facilitating the selection of the 3' splice site during exon ligation, this specific N-terminal acetylation may fine-tune its role within the dynamic spliceosomal machinery, potentially affecting its turnover rate or affinity for partner proteins like PRP18 and PRP22, although detailed functional distinctions solely attributable to this specific acetylation mark compared to the non-acetylated form remain an area of ongoing molecular investigation within the broader context of gene expression regulation.
