Summary: Enables guanyl-nucleotide exchange factor activity. Predicted to be involved in G protein-coupled receptor signaling pathway, coupled to cyclic nucleotide second messenger; adenylate cyclase-inhibiting G protein-coupled acetylcholine receptor signaling pathway; and chemical synaptic transmission. Located in several cellular components, including asymmetric synapse; neuronal cell body; and sarcolemma. Is active in glutamatergic synapse; postsynaptic density membrane; and presynaptic membrane. Biomarker of congestive heart failure. Orthologous to human CHRM4 (cholinergic receptor muscarinic 4). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
