Microtubule cross-linking factor 3 is a protein in humans that is encoded by the MTCL3 gene (previously SOGA3). In contrast to its paralogs MTCL1 and MTCL2, not much has been reported about the function of this protein, but it may be involved in autophagy. It has also been known as suppressor of glucose, autophagy associated 3 (SOGA3).
