Involved in cell cycle progression and cytokinesis. During the late steps of cytokinesis, anchors exocyst and SNARE complexes at the midbody, thereby allowing secretory vesicle-mediated abscission. Interacts with HOOK2. Interacts with EXOC6 and SNAPIN. Associates with the exocyst complex. Widely expressed with highest levels in testis and trachea. A chromosomal aberration involving CEP110 may be a cause of stem cell myeloproliferative disorder (MPD). Translocation t(8;9)(p12;q33) with FGFR1. MPD is characterized by myeloid hyperplasia, eosinophilia and T-cell or B-cell lymphoblastic lymphoma. In general it progresses to acute myeloid leukemia. The fusion protein CEP110-FGFR1 is found in the cytoplasm, exhibits constitutive kinase activity and may be responsible for the transforming activity. Truncated N-terminus. Contaminating sequence. Potential poly-A sequence. Contaminating sequence. Potential poly-A sequence.
