Summary
Acts upstream of or within locomotory exploration behavior. Predicted to be located in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Orthologous to human LSAMP (limbic system associated membrane protein). [provided by Alliance of Genome Resources, Nov 2024]
Expression
Biased expression in cerebellum adult (RPKM 15.7), cortex adult (RPKM 9.4) and 8 other tissues See more

What's a GeneRIF?
  1. Phenotyping neurons derived from the hippocampi of Lsamp(-/-), Ntm(-/-) and Lsamp(-/-)Ntm(-/-) mice was performed in parallel with behavioral testing. Lsamp appears to be an enhancer of neurite outgrowth as premature neuritogenesis in Ntm(-/-) neurons is apparent only in the presence of Lsamp. Lsamp appeared to be a positive regulator of apoptosis in the presence of Ntm.

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.
