Enables identical protein binding activity and mitogen-activated protein kinase p38 binding activity. Involved in several processes, including cell growth involved in cardiac muscle cell development; regulation of cellular biosynthetic process; and regulation of ion transport. Located in several cellular components, including Golgi apparatus; acrosomal vesicle; and nucleoplasm. Colocalizes with sarcolemma. Biomarker of allergic rhinitis; hypertension; hypogonadism; impotence; and obesity. Human ortholog(s) of this gene implicated in thoracic aortic aneurysm. Orthologous to human PRKG1 (protein kinase cGMP-dependent 1). [provided by Alliance of Genome Resources, Apr 2022]
