Summary: Enables phospholipase binding activity. Involved in several processes, including COP9 signalosome assembly; positive regulation of T cell differentiation in thymus; and positive regulation of T cell receptor signaling pathway. Acts upstream of or within TCR signalosome assembly. Located in cytoplasm. Part of TCR signalosome. Is expressed in testis; thymus; and thymus primordium. Orthologous to human TESPA1 (thymocyte expressed, positive selection associated 1). [provided by Alliance of Genome Resources, Apr 2022]

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.
