Ninein-like protein (NINL)

Ninein-like protein (NINL), also known as KIAA0980 and NLP, is a human centrosomal protein encoded by the NINL gene located on chromosome 20[3][5][6]. NINL is involved in microtubule organization, particularly nucleation and anchoring at the centrosome, and contributes to vesicle transport in photoreceptor cells[1][7]. It interacts with the γ-tubulin ring complex (γTuRC) and is regulated by cell cycle kinases such as Plk1 and Nek2, which control its phosphorylation and association with the centrosome[2][4]. NINL is implicated in the organization of the Golgi apparatus through its association with the dynein-dynactin complex[2]. Overexpression of NINL is observed in various human cancers, especially breast and lung carcinoma, where its gene amplification correlates with tumorigenic processes and genomic instability[4]. Variants in NINL are also associated with Heimler syndrome 2 and accommodative spasm[1]. While NINL is considered a promising target for research in cancer diagnostics and therapeutics, no direct drug interactions or established clinical inhibitors exist to date.

Drugs targeting this protein would likely affect cellular microtubule organization, mitotic spindle assembly, or centrosome function; however, no drug mechanisms have been established
