Lysophosphatidic acid treatment did not alter the expression and distribution of Homer1 in cortical neurons. Knockdown of Homer1 using specific siRNA partially prevented the LPA-induced neurotoxicity and ER stress. LPA induced intracellular Ca(2+) release could be partly prevented by downregulation of Homer1.

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.
