Protein phosphorylation is a reversible post-translational modification that is a critical component of almost all signaling pathways. Kinases regulate substrate proteins through phosphorylation, and nearly all proteins are phosphorylated to some extent. Crucially, breakdown in phosphorylation signaling is an underlying factor in many diseases, including cancer. Understanding how phosphorylation signaling mediates cellular pathways is crucial for understanding cell biology and human disease.
Targeted protein degradation (TPD) is a strategy to rapidly deplete a protein of interest (POI) and is applicable to any gene that is amenable to CRISPR-Cas9 editing. One TPD approach is the auxin-inducible degron (AID) system, which relies …

The goal of mitosis is to achieve faithful chromosome segregation; ensuring that the daughter cells inherit equal numbers of chromosomes. This is vital to cell health and viability and if mis-regulated can result in birth defects and disease such as cancer. There are many intricately regulated processes that occur throughout mitosis to achieve proper chromosome segregation, and one such example is the dynamic attachments formed between cytoskeletal structures, known as microtubules, and chromosomes, the carriers of genetic material. These attachments occur at structures called kinetochores, and the microtubules attached here are referred to as kinetochore-microtubules (k-MTs). These k-MTs are inherently …
