    Summary
    Enables microtubule minus-end binding activity and spectrin binding activity. Involved in several processes, including neuron projection development; regulation of cell morphogenesis; and regulation of microtubule polymerization. Located in microtubule minus-end. Implicated in complex cortical dysplasia with other brain malformations. [provided by Alliance of Genome Resources, Dec 2024]

      Title: Bi-allelic CAMSAP1 variants cause a clinically recognizable neuronal migration disorder.
    2. The CAMSAP1 CKK domain remodels its microtubule interaction site and changes the underlying polymer structure because the tubulin lattice conformation is not optimal for its binding. Thus, in contrast to many microtubule associated proteins, the human CKK domain can differentiate subtly specific tubulin conformations to enable microtubule minus-end recognition.

    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.
