Synthesis pass · prose summary of the discoveries below

DNAH10 is an inner dynein arm heavy chain essential for motile cilia and flagellar beating, left-right body patterning, and spermiogenesis. DNAH10 assembles with CFAP57, DYNLL1, and CCDC73 into the double-headed inner dynein arm f (IDAf) complex; loss of DNAH10 destabilizes these subunits, disrupts IDA ultrastructure, and causes ciliary dysfunction in respiratory epithelia, ependymal cells, and sperm flagella (PMID:40898283, PMID:34657236, PMID:37314648). Beyond its structural role in the axoneme, DNAH10 bridges the deubiquitinase UCHL3 to PACRG, stabilizing PACRG via deubiquitination and facilitating intra-manchette transport during sperm head and flagellum shaping (PMID:41058558). Bi-allelic loss-of-function mutations in DNAH10 cause primary ciliary dyskinesia with chronic respiratory disease, male infertility (MMAF/asthenoteratozoospermia), hydrocephalus, and situs defects, while ependymal monocilia dysfunction leads to Reissner fiber disassembly and scoliosis (PMID:37314648, PMID:34915022, PMID:29843777).

  1. 2019 Medium

    Before any ciliary role was defined, a Drosophila screen linked the DNAH10 ortholog to triglyceride homeostasis, raising the possibility of non-canonical functions for this dynein heavy chain.

    Evidence RNAi knockdown in Drosophila with triglyceride quantification

    PMID:30778226

    Open questions at the time
    • Mechanism connecting a ciliary dynein to lipid metabolism is unknown
    • Not replicated in vertebrate systems
    • Single phenotypic readout without mechanistic dissection
  2. 2021 High

    Genetic and ultrastructural studies in humans and zebrafish established DNAH10 as an IDA heavy chain required for sperm flagellar motility, ciliary-driven left-right patterning, and ependymal monocilia function, revealing that its loss causes MMAF/asthenoteratozoospermia, cardiac laterality defects, Reissner fiber disassembly, and scoliosis.

    Evidence Whole-exome sequencing in infertile men with TEM/SEM/IF; zebrafish CRISPR mutants with monocilia beat frequency measurement, Reissner fiber imaging, and in situ hybridization for laterality markers

    PMID:29843777 PMID:34657236 PMID:34915022

    Open questions at the time
    • Identity of the specific IDA sub-complex containing DNAH10 was unknown
    • Whether DNAH10 functions beyond the axoneme (e.g. during spermiogenesis) was not addressed
    • Human respiratory cilia phenotype had not yet been characterized
  3. 2023 High

    Extension to respiratory cilia and mouse genetics demonstrated that DNAH10 deficiency causes primary ciliary dyskinesia with IDA loss in both respiratory cilia and sperm, confirmed by knockout and knockin mouse models recapitulating chronic infection, hydrocephalus, and infertility.

    Evidence Exome sequencing in PCD patients; Dnah10-KO and knockin mice with immunostaining and TEM

    PMID:37314648

    Open questions at the time
    • Subunit composition of the DNAH10-containing IDA complex remained unresolved
    • Whether DNAH10 has roles outside the axonemal beat machinery was not explored
  4. 2024 Medium

    Correlative evidence in bovine sperm showed that axonemal DNAH10 protein levels decline under cryodamage in parallel with motility loss, supporting its functional requirement for flagellar beating.

    Evidence Western blot quantification and TEM in freeze-thawed bovine sperm with motility analysis

    PMID:38593909

    Open questions at the time
    • Correlative design; no causal manipulation of DNAH10 in bovine sperm
    • Does not distinguish whether DNAH10 loss is cause or consequence of structural collapse
  5. 2025 High

    Biochemical and proteomic work defined DNAH10 as a subunit of the double-headed IDAf complex (with CFAP57, DYNLL1, CCDC73) and revealed a second, non-axonemal function: DNAH10 bridges UCHL3 to PACRG, stabilizing PACRG via deubiquitination to support intra-manchette transport during spermiogenesis.

    Evidence Co-IP, proteomic analysis, immunostaining, and Dnah10-KO mice for IDAf complex; Co-IP and protein interaction assays with deubiquitination readouts in manchette studies

    PMID:40898283 PMID:41058558

    Open questions at the time
    • Structural basis of IDAf assembly and DNAH10 motor domain architecture remain unresolved
    • Whether the UCHL3-PACRG bridging function is independent of or integrated with axonemal assembly is unclear
    • Downstream cargo of DNAH10-dependent manchette transport not fully cataloged

Open questions

Synthesis pass · forward-looking unresolved questions
  • Key open questions include the atomic-resolution structure of the IDAf complex, the full catalog of DNAH10-dependent manchette cargo, and whether the triglyceride phenotype observed in Drosophila reflects a conserved metabolic role or a secondary consequence of ciliary defects.
  • No cryo-EM or crystal structure of DNAH10 or the IDAf complex
  • Lipid metabolism link lacks vertebrate replication or mechanistic explanation
  • Genotype-phenotype correlations across different DNAH10 mutations (missense vs. null) not systematically defined
