Bicaudal D cargo adaptor 2 is a protein that in humans is encoded by the BICD2 gene. [5] [6]
This gene is one of two human homologs of Drosophila bicaudal-D and a member of the Bicoid family. It has been implicated in dynein-mediated, minus end-directed motility along microtubules. It has also been reported to be a phosphorylation target of NIMA related kinase 8. Two alternative splice variants have been described. [6]
Mutations in BICD2 are associated with spinal muscular atrophy with lower extremity predominance type 2A and type 2B.
