Overview
SKAR Is involved in regulation of translation. Is preferentially associated with CBC-bound spliced mRNA-protein complexes during the pioneer round of mRNA translation. Contributes to enhanced translational efficiency of spliced over nonspliced mRNAs. Recruits activated ribosomal protein S6 kinase beta-1 I/RPS6KB1 to newly synthesized mRNA. Interacts with POLD2. Interacts with NCBP1 and EIF4A3. Associates with the multiprotein exon junction complex (EJC). Interacts with RPS6KB1 (activated). Interacts with ERH. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
