Involvement in diseaseⁱ

Carney complex 1 (CNC1)5 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionCNC is a multiple neoplasia syndrome characterized by spotty skin pigmentation, cardiac and other myxomas, endocrine tumors, and psammomatous melanotic schwannomas.

Intracardiac myxoma (INTMYX)

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionInheritance is autosomal recessive.

Primary pigmented nodular adrenocortical disease 1 (PPNAD1)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA rare bilateral adrenal defect causing ACTH-independent Cushing syndrome. Macroscopic appearance of the adrenals is characteristic with small pigmented micronodules observed in the cortex. Clinical manifestations of Cushing syndrome include facial and truncal obesity, abdominal striae, muscular weakness, osteoporosis, arterial hypertension, diabetes. PPNAD1 is most often diagnosed in patients with Carney complex, a multiple neoplasia syndrome. However it can also be observed in patients without other manifestations.

Acrodysostosis 1, with or without hormone resistance (ACRDYS1)7 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA form of skeletal dysplasia characterized by short stature, severe brachydactyly, facial dysostosis, and nasal hypoplasia. Affected individuals often have advanced bone age and obesity. Laboratory studies show resistance to multiple hormones, including parathyroid, thyrotropin, calcitonin, growth hormone-releasing hormone, and gonadotropin. However, not all patients show endocrine abnormalities.

Interactionⁱ

Subunit structureⁱ

The inactive holoenzyme is composed of two regulatory chains and two catalytic chains. Activation by cAMP releases the two active catalytic monomers and the regulatory dimer. PRKAR1A also interacts with RFC2; the complex may be involved in cell survival. Interacts with AKAP4. Interacts with RARA; the interaction occurs in the presence of cAMP or FSH and regulates RARA transcriptional activity. Interacts with the phosphorylated form of PJA2. Interacts with CBFA2T3 (By similarity). Interacts with PRKX; regulates this cAMP-dependent protein kinase. Interacts with C2orf88/smAKAP; this interaction may target PRKAR1A to the plasma membrane. Interacts with AICDA.By similarity6 Publications
