During interphase, GTSE1 localizes to the growing plus-end tip of microtubules by binding to the microtubule plus end protein MAPRE1 (EB1). This interaction involves two SKIP-like EB1-interaction motifs of GTSE1 and the C-terminal EB-homology (EBH) domain of MAPRE1. The interaction between GTSE1 and MAPRE1 is evolutionarily conserved. The interaction between GTSE1 and MAPRE1 at growing microtubule plus ends promotes cell migration, likely through microtubule-induced disassembly of focal adhesions. GTSE1 expression levels in G1 phase correlate with invasiveness of breast cancer cell lines (Scolz et al. 2012).
