Summary: Enables microtubule binding activity. Involved in several processes, including ciliary body morphogenesis; gonad development; and microtubule bundle formation involved in mitotic spindle midzone assembly. Located in microtubule; mitotic spindle midzone; and nucleus. Orthologous to human PRC1 (protein regulator of cytokinesis 1). [provided by Alliance of Genome Resources, Nov 2024]

What's a GeneRIF?

his phenotype therefore enabled us to identify factors promoting microtubule organization during anaphase, whose contributions are normally undetectable in wild-type worms; we found that SPD-1 (PRC1) bundles microtubules and KLP-18 (kinesin-12) likely sorts those bundles into a functional orientation capable of mediating chromosome segregation.

SPD-1-CYK-4 interaction through the CYK-4 C-terminal tail plays an important role in maintaining the mechanical integrity of the central spindle under tension
Title: Direct interaction between centralspindlin and PRC1 reinforces mechanical resilience of the central spindle.
The microtubule-bundling protein SPD-1/MAP-65 and BMK-1/kinesin-5 act as a brake opposing the force generated by the spindle midzone during Caenorhabditis elegans mitosis.
Title: Chromatids segregate without centrosomes during Caenorhabditis elegans mitosis in a Ran- and CLASP-dependent manner.
