Plays an essential role in neuronal cell migration. Localized specifically to the pericentriolar region. Isoform 1 and isoform 4 are expressed in spleen, lymph, thymus, tonsil and peripheral blood leukocytes, with isoform 1 expressed at higher levels. Isoform 4 is detected in K-562 leukemia cells and in the blood of precursor T lymphoblastic lymphoma (T-ALL) patients. A chromosomal aberration involving CEP85L is found in a patient with T-lymphoblastic lymphoma (T-ALL) and an associated myeloproliferative neoplasm (MPN) with eosinophilia. Translocation t(5;6)(q33-34;q23) with PDGFRB. The translocation fuses the 5'-end of CEP85L (isoform 4) to the 3'-end of PDGFRB. The disease is caused by variants affecting the gene represented in this entry. Belongs to the CEP85 family. Truncated N-terminus.
