Summaries for KLC2 Gene

Entrez Gene Summary for KLC2 Gene

  • The protein encoded by this gene is a light chain of kinesin, a molecular motor responsible for moving vesicles and organelles along microtubules. Defects in this gene are a cause of spastic paraplegia, optic atrophy, and neuropathy (SPOAN) syndrome. [provided by RefSeq, Mar 2016]

GeneCards Summary for KLC2 Gene

KLC2 (Kinesin Light Chain 2) is a Protein Coding gene. Diseases associated with KLC2 include Spastic Paraplegia, Optic Atrophy, And Neuropathy. Among its related pathways are Golgi-to-ER retrograde transport and Signaling by Rho GTPases. Gene Ontology (GO) annotations related to this gene include microtubule motor activity and kinesin binding. An important paralog of this gene is KLC4.

UniProtKB/Swiss-Prot for KLC2 Gene

  • Kinesin is a microtubule-associated force-producing protein that may play a role in organelle transport. The light chain may function in coupling of cargo to the heavy chain or in the modulation of its ATPase activity (By similarity).

  • Spastic paraplegia, optic atrophy, and neuropathy (SPOAN) [MIM:609541]: A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPOAN is characterized by spastic paraplegia with progressive joint contractures and spine deformities, loss of independent ambulation by age 10 years, sub-normal vision secondary to congenital optic atrophy, and neuropathy. Inheritance is autosomal recessive. {ECO:0000269 PubMed:26385635}. Note=The gene represented in this entry is involved in disease pathogenesis. The disease is caused by a homozygous deletion in the non-coding region of the KLC2 gene. {ECO:0000269 PubMed:26385635}.
