Summary: Enables dynein complex binding activity. Predicted to be involved in several processes, including microtubule cytoskeleton organization; positive regulation of neuron projection development; and regulation of microtubule depolymerization. Located in axon and centrosome. Is expressed in several structures, including alimentary system; genitourinary system; heart; nervous system; and primitive streak.

KATNB1 is a master regulator of multiple katanin enzymes in male meiosis and haploid germ cell development.
Title: KATNB1 is a master regulator of multiple katanin enzymes in male meiosis and haploid germ cell development.
Study uncovered an unexpected role of the p60-MIT and p80-CTD domains of katanin in the oligomerization and regulation of the protein. p80-CTD mediates the assembly of p60-MIT:p80-CTD heterodimers into heterotetramers that have an impact on katanin MT end and lattice binding as well as on the severing activity of the enzyme. The heterotetrameric structure of the p60-MIT:p80-CTD K555A/R591A mutant revealed a domain swap.
Title: Crystal Structure of a Heterotetrameric Katanin p60:p80 Complex.
This study structurally and functionally characterized the interaction between the two katanin subunits that is mediated by the p60-MIT domain and the p80 C-terminal domain (p80-CTD). p60-MIT and p80-CTD form a tight heterodimeric complex, whose high-resolution structure was determined by X-ray crystallography.
Title: Structural basis of katanin p60:p80 complex formation.
Katnb1 is ubiquitously expressed during embryonic development, although a stronger expression is seen in the crown cells of the gastrulation organizer, the murine node. Furthermore, null and hypomorphic Katnb1 gene mutations show a novel correlation between Katnb1 dysregulation and the development of impaired left-right signaling, including cardiac malformations.
Title: Mutations in the Katnb1 gene cause left-right asymmetry and heart defects.
Collectively these data demonstrate that katanin p80 serves an essential and evolutionarily conserved role in several aspects of male germ cell development
Title: An essential role for katanin p80 and microtubule severing in male gamete production.
Cul3-deficient cells or Ctb9/KLHDC5-deficient cells show an increase in p60/katanin levels, indicating that Cul3/Ctb9/KLHDC5 is required for efficient p60/katanin removal
Title: The Cul3/Klhdc5 E3 ligase regulates p60/katanin and is required for normal mitosis in mammalian cells.

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.
