Bicaudal D cargo adaptor 2 is aprotein that in humans is encoded by theBICD2gene.[5][6]
This gene is one of two humanhomologs ofDrosophila bicaudal-D and a member of theBicoid family. It has been implicated indynein-mediated, minus end-directedmotility alongmicrotubules. It has also been reported to be aphosphorylation target of NIMA relatedkinase 8. Two alternative splice variants have been described.[6]
Mutations inBICD2 are associated with spinal muscular atrophy with lower extremity predominancetype 2A andtype 2B.
