Lemur tyrosine kinase-3 (LMTK3; also known as LMR3, TYKLM3, and KIAA 1883) is a predicted dual-specificity protein kinase whose expression levels have been implicated in cancer cell invasion, endocrine resistance, poor prognosis, and overall tumor progression in different types of malignancies (Giamas et al., 2011; Zhao et al., 2013). Here, LMTK3 is linked to neoplasm.
