What's a GeneRIF?

SALM4 negatively regulates NMDA receptor function and fear memory consolidation.
Title: SALM4 negatively regulates NMDA receptor function and fear memory consolidation.
SALM4 cis-interacts with SALM3, inhibits trans-synaptic SALM3 interaction with presynaptic LAR family receptor tyrosine phosphatases and suppresses SALM3-dependent presynaptic differentiation.
Title: SALM4 suppresses excitatory synapse development by cis-inhibiting trans-synaptic SALM3-LAR adhesion.
Data show that the C-terminal PDZ binding domains of synaptic adhesion-like molecules (SALMs)1-3 are required for neurite outgrowth, and that the N-termini of SALMs 2 and 4 are alsoinvolved in neurite outgrowth.
Title: Synaptic adhesion-like molecules (SALMs) promote neurite outgrowth.

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.
