Function of mitotic spindle during mitosis
WebHere, we identify the Ubiquitin-Binding Protein 2-Like (UBAP2L) that controls both the localization and the protein stability of PLK1. We demonstrate that UBAP2L is a spindle-associated protein whose depletion leads to severe mitotic defects. UBAP2L-depleted cells are characterized by increased PLK1 protein levels and abnormal PLK1 accumulation ... WebFeb 4, 2024 · The four stages of mitosis are known as prophase, metaphase, anaphase, telophase. Additionally, we’ll mention three other intermediary stages (interphase, prometaphase, and cytokinesis) that …
