    Summary
    Enables protein kinase binding activity. Involved in cilium assembly. Acts upstream of or within cerebrospinal fluid circulation; mucociliary clearance; and sperm axoneme assembly. Located in axonemal central apparatus and sperm flagellum. Orthologous to human SPAG16 (sperm associated antigen 16). [provided by Alliance of Genome Resources, Nov 2024]

    What's a GeneRIF?
    1. In this work, we performed a quantitative analysis of the expression of Spag6 and Spag16 genes in parallel with the immune-localization of the proteins in several tissues of adult mice.

    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 (2) contains an alternate 5'-most exon in the 5' UTR and lacks a portion of the 5' coding region compared to variant 1. These differences cause translation initiation at a downstream AUG and result in an isoform (2; also known as Spag16S) with a shorter N-terminus, compared to isoform 1.
