Kinesin family member 22 mRNA (KIF22 mRNA) (KIF22 mRNA)

Kinesin family member 22 (KIF22) mRNA encodes a kinesin-10 family motor protein, also known as Kinesin-like DNA-binding protein (KID), which is essential for chromosome alignment and spindle assembly during mitosis [UniProt: P33176]. The KIF22 protein is unique for its ability to bind both microtubules and chromatin, providing the polar ejection force necessary for pushing chromosomes toward the metaphase plate [PubMed: 11071911]. In various malignancies, including breast, lung, and colorectal cancers, KIF22 mRNA is frequently overexpressed, which correlates with increased cell proliferation and poor clinical outcomes [PubMed: 29130528]. Consequently, KIF22 mRNA has emerged as a therapeutic target for RNA-based interventions, such as small interfering RNAs (siRNAs) and antisense oligonucleotides (ASOs), designed to deplete KIF22 levels and induce mitotic arrest or apoptosis in tumor cells [PubMed: 25670303]. Beyond its role in oncology, specific gain-of-function mutations in the KIF22 gene are the underlying cause of spondyloepimetaphyseal dysplasia with joint laxity type 1 (SEMDJL1), a rare skeletal disorder [PubMed: 22036171]. Therapeutic strategies targeting KIF22 mRNA must navigate the challenge of achieving tumor-specific delivery while avoiding disruption of mitosis in healthy, rapidly dividing tissues. As a regulator of the "polar ejection force," KIF22 is a critical component of the mitotic machinery, making its mRNA a high-interest target for precision medicine in hyper-proliferative diseases.
