Anchoring protein that mediates the subcellularcompartmentation of cAMP-dependent protein kinase (PKA type II)(PubMed:9473338). Acts as an anchor for a PKA-signaling complexonto mitotic chromosomes, which is required for maintenance ofchromosomes in a condensed form throughout mitosis. Recruitscondensin complex subunit NCAPD2 to chromosomes required forchromatin condensation; the function appears to be independentfrom PKA-anchoring (PubMed:10601332, PubMed:10791967,PubMed:11964380). May help to deliver cyclin D/E to CDK4 tofacilitate cell cycle progression (PubMed:14641107). Required forcell cycle G2/M transition and histone deacetylation duringmitosis. In mitotic cells recruits HDAC3 to the vicinity ofchromatin leading to deacetylation and subsequent phosphorylationat 'Ser-10' of histone H3; in this function may act redundantlywith AKAP8L (PubMed:16980585). Involved in nuclear retention ofRPS6KA1 upon ERK activation thus inducing cell proliferation(PubMed:22130794). May be involved in regulation of DNAreplication by acting as scaffold for MCM2 (PubMed:12740381).Enhances HMT activity of the KMT2 family MLL4/WBP7 complex and isinvolved in transcriptional regulation. In a teratocarcinoma cellline is involved in retinoic acid-mediated induction ofdevelopmental genes implicating H3 'Lys-4' methylation(PubMed:23995757). May be involved in recruitment of active CASP3to the nucleus in apoptotic cells (PubMed:16227597). May act as acarrier protein of GJA1 for its transport to the nucleus(PubMed:26880274). Seems to involved in modulation of rDNAtranscription. Preferentially binds GC-rich DNA in vitro andassociates to GC-rich ribosomal RNA promoters (PubMed:26683827).Involved in modulation of Toll-like receptor signaling. Requiredfor the cAMP-dependent suppression of TNF-alpha in early stages ofLPS-induced macrophage activation; the function probablyimplicates targeting of PKA to NFKB1 (By similarity).{ECO:0000250|UniProtKB:Q63014, ECO:0000250|UniProtKB:Q9DBR0,ECO:0000269|PubMed:10601332, ECO:0000269|PubMed:10791967,ECO:0000269|PubMed:11964380, ECO:0000269|PubMed:16980585,ECO:0000269|PubMed:22130794, ECO:0000269|PubMed:26683827,ECO:0000269|PubMed:26880274, ECO:0000305|PubMed:14641107,ECO:0000305|PubMed:9473338}. | Anchoring protein that mediates the subcellularcompartmentation of cAMP-dependent protein kinase (PKA type II)(PubMed:9473338).
