Genetic interaction between central pair apparatus genes CFAP221, CFAP54, and SPEF2 in mouse models of primary ciliary dyskinesia.
Title: Genetic interaction between central pair apparatus genes CFAP221, CFAP54, and SPEF2 in mouse models of primary ciliary dyskinesia.
Mutations in SPEF2 are associated with multiple morphological abnormalities of the sperm flagella and primary ciliary dyskinesia.
Title: Novel mutations in SPEF2 causing different defects between flagella and cilia bridge: the phenotypic link between MMAF and PCD.
Investigated the function of SPEF2 during spermatogenesis using a male germ cell-specific Spef2 knockout model. In addition to defects in sperm tail development, we observed a duplication of the basal body and failure in manchette migration resulting in an abnormal head shape.
Title: SPEF2 functions in microtubule-mediated transport in elongating spermatids to ensure proper male germ cell differentiation.
Data indicate that SPEF2 is required for cilia function/motility; defect in SPEF2 results in primary ciliary dyskinesia. SPEF2 plays important role in spermatogenesis and sperm flagellum assembly. (base/AA sequence data submitted to GenBank)
Title: Loss of SPEF2 function in mice results in spermatogenesis defects and primary ciliary dyskinesia.
The crucial importance of SPEF2 in sperm differentiation and involvement of SPEF2 in structuring of the sperm tail.
Title: Expression of SPEF2 during mouse spermatogenesis and identification of IFT20 as an interacting protein.

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.

Description

Transcript Variant: This variant (3) lacks numerous 3' exons and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. It encodes isoform 3 which is shorter and has a distinct C-terminus, compared to isoform 1.
