Summaries for PRRT2 Gene

Entrez Gene Summary for PRRT2 Gene

  • This gene encodes a transmembrane protein containing a proline-rich domain in its N-terminal half. Studies in mice suggest that it is predominantly expressed in brain and spinal cord in embryonic and postnatal stages. Mutations in this gene are associated with episodic kinesigenic dyskinesia-1. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

    340 amino acids
    Molecular mass:
    34945 Da
    Quaternary structure:
    • Component of the outer core of AMPAR complex. AMPAR complex consists of an inner core made of 4 pore-forming GluA/GRIA proteins (GRIA1, GRIA2, GRIA3 and GRIA4) and 4 major auxiliary subunits arranged in a twofold symmetry. One of the two pairs of distinct binding sites is occupied either by CNIH2, CNIH3 or CACNG2, CACNG3. The other harbors CACNG2, CACNG3, CACNG4, CACNG8 or GSG1L. This inner core of AMPAR complex is complemented by outer core constituents binding directly to the GluA/GRIA proteins at sites distinct from the interaction sites of the inner core constituents. Outer core constituents include at least PRRT1, PRRT2, CKAMP44/SHISA9, FRRS1L and NRN1. The proteins of the inner and outer core serve as a platform for other, more peripherally associated AMPAR constituents. Alone or in combination, these auxiliary subunits control the gating and pharmacology of the AMPAR complex and profoundly impact their biogenesis and protein processing (By similarity).

Disorders for PRRT2 Gene

(3) OMIM Diseases for PRRT2 Gene (614386)


  • Episodic kinesigenic dyskinesia 1 (EKD1) [MIM:128200]: An autosomal dominant neurologic condition characterized by recurrent and brief attacks of abnormal involuntary movements, triggered by sudden voluntary movement. These attacks usually have onset during childhood or early adulthood and can involve dystonic postures, chorea, or athetosis. {ECO:0000269 PubMed:22101681, ECO:0000269 PubMed:22120146, ECO:0000269 PubMed:22131361, ECO:0000269 PubMed:22209761}. Note=The disease is caused by mutations affecting the gene represented in this entry. Disease-causing mutations that produce truncation of the C-terminus of the protein alter subcellular location, from plasma membrane to cytosplasm (PubMed:22101681). {ECO:0000269 PubMed:22101681}.
  • Convulsions, familial infantile, with paroxysmal choreoathetosis (ICCA) [MIM:602066]: A syndrome characterized by clinical features of benign familial infantile seizures and episodic kinesigenic dyskinesia. Benign familial infantile seizures is a disorder characterized by afebrile seizures occurring during the first year of life, without neurologic sequelae. Paroxysmal choreoathetosis is a disorder of involuntary movements characterized by attacks that occur spontaneously or are induced by a variety of stimuli. {ECO:0000269 PubMed:22243967}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Seizures, benign familial infantile 2 (BFIS2) [MIM:605751]: An autosomal dominant disorder in which afebrile seizures occur in clusters during the first year of life, without neurologic sequelae. {ECO:0000269 PubMed:22243967, ECO:0000269 PubMed:22399141, ECO:0000269 PubMed:22623405}. Note=The disease is caused by mutations affecting the gene represented in this entry.
