Summary: Enables cargo adaptor activity; clathrin heavy chain binding activity; and small GTPase binding activity. Involved in several processes, including mRNA transport; oocyte differentiation; and regulation of vesicle-mediated transport. Located in cytoplasm. Colocalizes with clathrin-coated endocytic vesicle membrane. Is expressed in several structures, including adult brain; embryonic/larval midgut primordium; epidermis; germline cell; and gut section. Used to study spinal muscular atrophy with lower extremity predominant 2A. Human ortholog(s) of this gene implicated in spinal muscular atrophy with lower extremity predominant 2A and spinal muscular atrophy with lower extremity predominant 2B. Orthologous to several human genes including BICD1 (BICD cargo adaptor 1). [provided by Alliance of Genome Resources, Dec 2024]

Role of BicDR in bristle shaft construction and support of BicD functions.
Title: Role of BicDR in bristle shaft construction and support of BicD functions.
Coiled-coil registry shifts in the F684I mutant of Bicaudal D result in cargo-independent activation of dynein motility.
Title: Coiled-coil registry shifts in the F684I mutant of Bicaudal D result in cargo-independent activation of dynein motility.
the RNA is required for robust activation of dynein motility. We show that a cis-acting RNA localisation signal promotes the interaction of Egl with BicD, which licenses the latter protein to recruit dynein and dynactin. Our data support a model for BicD activation based on RNA-induced occupancy of two Egl-binding sites on the BicD dimer.
Title: RNA-directed activation of cytoplasmic dynein-1 in reconstituted transport RNPs.
artificially dimerized Egl activates dynein-dynactin-BicD in the absence of mRNA. The ability of mRNA cargo to orchestrate the activation of the mRNP (messenger ribonucleotide protein) complex is an elegant way to ensure that only cargo-bound motors are motile.
Title: Recruitment of two dyneins to an mRNA-dependent Bicaudal D transport complex.
To study the pathological consequences of BICD2 mutations in vivo, and to address the controversial debate whether two of these mutations are neuron or muscle specific, we generated the first Drosophila model of spinal muscular atrophy-2.
Title: Novel insights into SMALED2: BICD2 mutations increase microtubule stability and cause defects in axonal and NMJ development.
Bic-D is also required to transport Chc mRNA into the oocyte and for transport and proper localization of Chc protein to the oocyte cortex.
Title: Clathrin heavy chain plays multiple roles in polarizing the Drosophila oocyte downstream of Bic-D.
2.2 A resolution crystal structure of a cargo-binding region of the dynein adaptor Bicaudal-D (BicD), which reveals a parallel coiled-coil homodimer
Title: Bicaudal-D uses a parallel, homodimeric coiled coil with heterotypic registry to coordinate recruitment of cargos to dynein.
Results implicate BicD as a new player in clathrin-associated trafficking processes and show a novel requirement for microtubule-based motor transport in the synaptic vesicle cycle.
Title: Bicaudal-D binds clathrin heavy chain to promote its transport and augments synaptic vesicle recycling.
while BicD might contribute to recruitment of dynein to the cargo it is not absolutely required for such dynein localization
Title: BicaudalD actively regulates microtubule motor activity in lipid droplet transport.
We propose that Msn functions together with Bic-D to regulate the apical localization of dynein in generating directed nuclear migration within differentiating R-cell precursor cells.
