Description

AKAP8, also known as A-kinase anchor protein 95 kDa, serves as a critical scaffolding protein that localizes protein kinase A to specific subcellular compartments, playing essential roles in chromatin condensation during mitosis and DNA replication regulation. This nuclear matrix protein has garnered significant research interest for its involvement in cell cycle progression and its emerging connections to cancer biology, making it a valuable target for investigators studying fundamental cellular processes.

This recombinant monoclonal antibody, generated from clone 16E6 in rabbit host, offers the reproducibility and consistency that demanding research applications require. Because recombinant antibodies are produced from defined genetic sequences rather than traditional hybridoma methods, researchers benefit from lot-to-lot uniformity that supports long-term studies and ensures comparable results across experiments. The affinity-purified rabbit IgG format provides excellent signal-to-noise characteristics while maintaining specificity against the human AKAP8 peptide immunogen, with validated cross-species reactivity extending to mouse samples.

Validation studies demonstrate robust performance across multiple experimental platforms. Immunohistochemistry applications have been confirmed in both paraffin-embedded mouse kidney tissue and human colorectal cancer sections using citrate buffer antigen retrieval, with recommended dilutions ranging from 1:50 to 1:200. Immunofluorescence staining in HeLa cells reveals clear nuclear localization patterns consistent with AKAP8's known biology, while flow cytometry analysis of the same cell line shows distinct positive population shifts compared to isotype controls.

For cell biology researchers investigating nuclear architecture, cell cycle regulation, or PKA signaling compartmentalization, this antibody provides a reliable tool with demonstrated versatility across tissue and cellular analysis workflows.

Target Background

Function

Anchoring protein that mediates the subcellular compartmentation of cAMP-dependent protein kinase (PKA type II). Acts as an anchor for a PKA-signaling complex onto mitotic chromosomes, which is required for maintenance of chromosomes in a condensed form throughout mitosis. Recruits condensin complex subunit NCAPD2 to chromosomes required for chromatin condensation; the function appears to be independent from PKA-anchoring. May help to deliver cyclin D/E to CDK4 to facilitate cell cycle progression. 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 may act redundantly with AKAP8L. Involved in nuclear retention of RPS6KA1 upon ERK activation thus inducing cell proliferation. May be involved in regulation of DNA replication by acting as scaffold for MCM2. Enhances HMT activity of the KMT2 family MLL4/WBP7 complex and is involved in transcriptional regulation. In a teratocarcinoma cell line is involved in retinoic acid-mediated induction of developmental genes implicating H3 'Lys-4' methylation. May be involved in recruitment of active CASP3 to the nucleus in apoptotic cells. May act as a carrier protein of GJA1 for its transport to the nucleus. May play a repressive role in the regulation of rDNA transcription. Preferentially binds GC-rich DNA in vitro. In cells, associates with ribosomal RNA (rRNA) chromatin, preferentially with rRNA promoter and transcribed regions. Involved in modulation of Toll-like receptor signaling. Required for the cAMP-dependent suppression of TNF-alpha in early stages of LPS-induced macrophage activation; the function probably implicates targeting of PKA to NFKB1.
