AKAP4

A-kinase anchor protein 4 is an is_associated_with::enzyme that in humans is encoded by the AKAP4 is_associated_with::gene.

Function
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 is_associated_with::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 is localized to the sperm is_associated_with::flagellum and may be involved in the regulation of sperm motility. Alternative splicing of this gene results in two transcript variants encoding different isoforms.

Interactions
AKAP4 has been shown to interact with:
 * is_associated_with::AKAP3, and
 * is_associated_with::PRKAR1A.
