Echinoderm Microtubule Associated Protein Like Protein 3 (EML3)

EML3 is a nuclear microtubule-binding protein required for the correct alignment of chromosomes in metaphase.An important subset of mitotic microtubule-binding proteins localises to the nucleus in interphase and essentially contributes to spindle formation and function after nuclear envelope breakdown.EML3 colocalises with spindle microtubules throughout all mitotic stages. In interphase, EML3 colocalised with cytoplasmic microtubules and accumulated in interphase nuclei. Using YFP-fusion constructs of EML3, Functional analysis of EML3 using time-lapse fluorescence microscopy and detailed end-point analysis of phenotypes after siRNA knockdown demonstrates an important role for EML3 in correct metaphase chromosome alignment.
