Summary: Enables GTP-dependent protein binding activity. Involved in several processes, including anterograde synaptic vesicle transport; negative regulation of synaptic assembly at neuromuscular junction; and positive regulation of insulin secretion. Located in axon terminus and dendrite. Part of microtubule associated complex. Is expressed in adult head and larval central nervous system. Used to study nervous system disease. Human ortholog(s) of this gene implicated in several diseases, including Charcot-Marie-Tooth disease type 2A1; NESCAV syndrome; carcinoma (multiple); hereditary sensory neuropathy (multiple); and hereditary spastic paraplegia (multiple). Orthologous to several human genes including KIF1A (kinesin family member 1A). [provided by Alliance of Genome Resources, Oct 2024]

What's a GeneRIF?

Prd1, alpha-Adaptin, and Unc-104 act in a common pathway to promote dendrite pruning by down-regulating Neuroglian protein.
Title: Prd1 associates with the clathrin adaptor α-Adaptin and the kinesin-3 Imac/Unc-104 to govern dendrite pruning in Drosophila.
provide novel insights into the role of Unc-104 in synapse maturation
Title: The KIF1A homolog Unc-104 is important for spontaneous release, postsynaptic density maturation and perisynaptic scaffold organization.
These studies at the Drosophila neuromuscular junction indicate that many synaptic defects in unc-104-null mutants are mediated independently of Unc-104's transport function, via the Wallenda (Wnd)/DLK MAP kinase axonal damage signaling pathway.
Title: Restraint of presynaptic protein levels by Wnd/DLK signaling mediates synaptic defects associated with the kinesin-3 motor Unc-104.
Unc-104 critically restricts neuromuscular junction growth and dendrite branch morphogenesis.
Title: The kinesin-3, unc-104 regulates dendrite morphogenesis and synaptic development in Drosophila.
Drosophila Unc-104 has neuronal functions that are distinct from those of the classic anterograde axonal motor, kinesin-1.
Title: Identification of an axonal kinesin-3 motor for fast anterograde vesicle transport that facilitates retrograde transport of neuropeptides.
Our data thus indicate that Imac transports components required for synaptic maturation and provide insight into presynaptic maturation as a process that can be differentiated from axon outgrowth and targeting.
Title: A Drosophila kinesin required for synaptic bouton formation and synaptic vesicle transport.
