AKAP-5
The A-kinase anchor proteins (AKAPs) are a group of structurally diverse proteins, which have the common function of binding to the regulatory subunit of protein kinase A (PKA) and confining the holoenzyme to discrete locations within the cell. This gene encodes a member of the AKAP family. The encoded protein binds to the RII-beta regulatory subunit of PKA, and also to protein kinase C and the phosphatase calcineurin. It is predominantly expressed in cerebral cortex and may anchor the PKA protein at postsynaptic densities (PSD) and be involved in the regulation of postsynaptic events. It is also expressed in T lymphocytes and may function to inhibit interleukin-2 transcription by disrupting calcineurin-dependent dephosphorylation of NFAT. [provided by RefSeq, Jul 2008]
Forensic Context
A study in mice demonstrated that the AKAP5 was downregulated 10.897-fold at 12 hours post-incised skeletal muscle injury, as identified by DNA microarray analysis [Gaballah et al. DOI:10.1016/j.forsciint.2016.06.027]. In human neonates with hypoxic-ischemic encephalopathy, whole-blood RNA sequencing identified the AKAP5 as one of 11 significant genes commonly associated with adverse outcomes across two distinct cohorts, where it was downregulated in a high-income country cohort but upregulated in a South Asia cohort [Montaldo et al. DOI:10.1001/jamanetworkopen.2023.54433].
