Also known as: X11L; XllL; mXllL; X11-like
Summary: Predicted to enable amyloid-beta binding activity and identical protein binding activity. Involved in presynaptic modulation of chemical synaptic transmission. Acts upstream of or within several processes, including chemical synaptic transmission; in utero embryonic development; and locomotory behavior. Is active in Schaffer collateral - CA1 synapse. Is expressed in several structures, including alimentary system; nervous system; respiratory system; sensory organ; and skeleton. Orthologous to human APBA2 (amyloid beta precursor protein binding family A member 2). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in CNS E18 (RPKM 37.9), cortex adult (RPKM 35.0) and 7 other tissues See more

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.
