Summary: Predicted to enable molecular condensate scaffold activity; protein kinase binding activity; and signaling receptor complex adaptor activity. Predicted to be involved in several processes, including cell surface receptor signaling pathway; intracellular signaling cassette; and membrane raft distribution. Predicted to act upstream of or within gene expression and lymphocyte homeostasis. Predicted to be located in Golgi apparatus; cell-cell junction; and membrane. Predicted to be part of COP9 signalosome and TCR signalosome. Predicted to be active in immunological synapse. Human ortholog(s) of this gene implicated in immunodeficiency 52. Orthologous to human LAT (linker for activation of T cells). [provided by Alliance of Genome Resources, Apr 2025]

chemotaxis toward antigen is controlled in mast cells by a cross-talk among FcepsilonRI, tetraspanin CD9, transmembrane adaptor proteins NTAL and LAT, and cytoskeleton-regulatory proteins of the ERM family

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.
