Summary: Predicted to enable several functions, including scaffold protein binding activity; transmembrane transporter binding activity; and type 5 metabotropic glutamate receptor binding activity. Predicted to be a structural constituent of postsynapse. Involved in regulation of monoatomic ion transport and regulation of postsynaptic neurotransmitter receptor activity. Acts upstream of or within several processes, including behavioral response to cocaine; skeletal muscle contraction; and skeletal muscle fiber development. Located in several cellular components, including apical part of cell; myofibril; and postsynapse. Is active in glutamatergic synapse; postsynaptic cytosol; and postsynaptic density. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human HOMER1 (homer scaffold protein 1). [provided by Alliance of Genome Resources, Dec 2024]

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.

Status: VALIDATED

Description

Transcript Variant: This variant (M, also known as Vesl-1M) lacks several 3' exons but contains an alternate 3' terminal exon, and it thus differs in the 3' coding region and 3' UTR, compared to variant L. The encoded isoform (M) has a shorter and distinct C-terminus, compared to isoform L.

Status: VALIDATED

Description

Transcript Variant: This variant (S, also known as homer-1a or Vesl-1S) lacks several 3' exons but contains a 3' terminal exon that extends past a splice site that is used in variant L, resulting in a novel 3' coding region and 3' UTR, compared to variant L. The encoded isoform (S) has a shorter and distinct C-terminus, compared to isoform L.
