Summaries for DLGAP2 Gene

Entrez Gene Summary for DLGAP2 Gene

  • The product of this gene is a membrane-associated protein that may play a role in synapse organization and signalling in neuronal cells. This gene is biallelically expressed in the brain, however, only the paternal allele is expressed in the testis (PMID:18055845). Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jun 2014]

GeneCards Summary for DLGAP2 Gene

DLGAP2 (Discs Large Homolog Associated Protein 2) is a Protein Coding gene. An important paralog of this gene is DLGAP3.

UniProtKB/Swiss-Prot for DLGAP2 Gene

  • May play a role in the molecular organization of synapses and neuronal cell signaling. Could be an adapter protein linking ion channel to the subsynaptic cytoskeleton. May induce enrichment of PSD-95/SAP90 at the plasma membrane.
