Kif1C is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
KIF1C (Kinesin Family Member 1C) is a gene encoding a member of the kinesin-3 family of motor proteins. KIF1C mediates intracellular transport along microtubules and is particularly important in ER-to-Golgi trafficking, axonal transport, and neuronal function. Mutations in KIF1C are associated with hereditary spastic paraplegia and related neurological disorders.

The KIF1C gene consists of 27 exons spanning approximately 35 kb of genomic DNA on chromosome 17p13.2. The coding sequence is highly conserved across mammals, reflecting its essential role in cellular transport functions. Alternative splicing produces multiple transcript variants with tissue-specific expression patterns.
KIF1C is a member of the kinesin-3 family, characterized by several distinct domains:
The motor protein functions as a homodimer, with each subunit contributing to processive movement along microtubules.
KIF1C performs essential functions in neuronal and non-neuronal cells:
As a processive kinesin motor, KIF1C transports various cargoes along microtubule tracks:
In neurons, KIF1C contributes to:
KIF1C plays a major role in the secretory pathway:
KIF1C is widely expressed in the nervous system:
Expression is also detected in non-neuronal tissues, including fibroblasts and immune cells, where it participates in general membrane trafficking.
KIF1C mutations cause autosomal recessive hereditary spastic paraplegia:
Pathogenic mechanisms include:
KIF1C mutations can cause cerebellar ataxia:
