Echinoderm microtubule-associated protein -like protein 5 in anterior temporal neocortex of patients with intractable epilepsy
Objective(s):EMAP-like Protein 5 (EML5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. The aim of this study was to investigate the expression profile of EML5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (IE). Materials and Methods:Western blot assays were performed to determine EML5 expression in 36 su...
متن کاملCentrophilin: a novel mitotic spindle protein involved in microtubule nucleation
A novel protein has been identified which may serve a key function in nucleating spindle microtubule growth in mitosis. This protein, called centrophilin, is sequentially relocated from the centromeres to the centrosomes to the midbody in a manner dependent on the mitotic phase. Centrophilin was initially detected by immunofluorescence with a monoclonal, primate-specific antibody (2D3) raised a...
متن کاملNuSAP, a novel microtubule-associated protein involved in mitotic spindle organization
Here, we report on the identification of nucleolar spindle-associated protein (NuSAP), a novel 55-kD vertebrate protein with selective expression in proliferating cells. Its mRNA and protein levels peak at the transition of G2 to mitosis and abruptly decline after cell division. Microscopic analysis of both fixed and live mammalian cells showed that NuSAP is primarily nucleolar in interphase, a...
متن کاملSuppression of microtubule assembly kinetics by the mitotic protein TPX2.
TPX2 is a widely conserved microtubule-associated protein that is required for mitotic spindle formation and function. Previous studies have demonstrated that TPX2 is required for the nucleation of microtubules around chromosomes; however, the molecular mechanism by which TPX2 promotes microtubule nucleation remains a mystery. In this study, we found that TPX2 acts to suppress tubulin subunit o...
متن کاملStudies of a microtubule-associated protein using a monoclonal antibody elicited against mammalian mitotic spindles
We have devised a procedure for the identification of individual molecules which are associated with the mitotic spindle apparatus and cytoskeleton in mammalian cells. We prepared monoclonal antibody-producing hybridomas by immunizing mice with mitotic spindles isolated from cultured HeLa cells. Among several antibody-producing clones obtained, one hybridoma (22MA2) produced an antibody that re...
