AKAP8L rabbit pAb

Could play a role in constitutive transport element (CTE)-mediated gene expression by association with DHX9. Increases CTE-dependent nuclear unspliced mRNA export . Proposed to target PRKACA to the nucleus but does not seem to be implicated in the binding of regulatory subunit II of PKA . May be involved in nuclear envelope breakdown and chromatin condensation. May be involved in anchoring nuclear membranes to chromatin in interphase and in releasing membranes from chromating at mitosis . May regulate the initiation phase of DNA replication when associated with TMPO isoform Beta . Required for cell cycle G2/M transition and histone deacetylation during mitosis. In mitotic cells recruits HDAC3 to the vicinity of chromatin leading to deacetylation and subsequent phosphorylation at 'Ser-10' of histone H3; in this function seems to act redundantly with AKAP8 . May be involved in regulation of pre-mRNA splicing . ; (Microbial infection) In case of EBV infection, may target PRKACA to EBNA-LP-containing nuclear sites to modulate transcription from specific promoters. ; (Microbial infection) Can synergize with DHX9 to activate the CTE-mediated gene expression of type D retroviruses. ; (Microbial infection) In case of HIV-1 infection, involved in the DHX9-promoted annealing of host tRNA(Lys3) to viral genomic RNA as a primer in reverse transcription; in vitro negatively regulates DHX9 annealing activity.
