Facts about Serine/threonine-protein phosphatase 2B catalytic subunit alpha isoform.
In response to increased Ca(2+) levels, dephosphorylates and activates phosphatase SSH1 which results in cofilin dephosphorylation (PubMed:15671020). In response to increased Ca(2+) levels after mitochondrial depolarization, dephosphorylates DNM1L inducing DNM1L translocation into the mitochondrion (PubMed:18838687).

Cytoplasm. Cell membrane; Peripheral membrane protein. Cell membrane, sarcolemma. Cytoplasm, myofibril, sarcomere, Z line. Cell projection, dendritic spine. Colocalizes with ACTN1 and MYOZ2 at the Z line in heart and skeletal muscle (By similarity). Recruited to the cell membrane by scaffold protein AKAP5 following L-type Ca(2+)-channel activation (PubMed:22343722).
