KIF1A.ORG exists to accelerate discovery of treatments for this generation of people affected by KIF1A Associated Neurological Disorder (KAND). In addition to ongoing R&D collaborations, KIF1A.ORG funds strategic projects powered to rapidly develop treatment for KIF1A Associated Neurological Disorder.

Chung Lab 

Wendy Chung, MD, PhD, and her team at Columbia University Medical Center in New York City have been our relentless partners since the founding of KIF1A.ORG in 2017. Chung Lab spearheads a robust preclinical KAND program, including a global patient registry and longitudinal natural history study; disease modeling with patient-derived stem cell lines (iPSCs) and animal models; biomarker studies; KAND severity scale and clinical disease characterization. Dr. Chung has been our sherpa from day one, and sees many of our KAND families in her clinic. The Chung Lab’s work has drastically improved our understanding of KIF1A gene function, clinical care, and targeted strategies to develop treatments and cures for KAND. Dr. Chung also leads several collaborations within the scientific community focused on bringing treatment to families affected by mutations in KIF1A.  If you’re a patient or caregiver, visit our Natural History Study page to learn how you can get involved to advance KAND research further.

Recent Research

  • Genotype and defects in microtubule-based motility correlate with clinical severity in KIF1A Associated Neurological Disorder (2020)
  • Disease severity in KIF1A Associated Neurological Disorders (KAND) is correlated with variant location (2019)

McKenney Lab

The McKenney lab at University of California, Davis uses state-of-the-art biochemical and biophysical methods to uncover the molecular basis of defects in KIF1A motor proteins containing mutations known to cause KAND. We have focused our initial efforts on the P305L mutation, as this mutation was previously uncharacterized and little was known about how this mutation impacts the KIF1A motor. We are producing normal and mutant KIF1A motor proteins and assaying their ability to move along microtubules using single-molecule microscopy that allows us to visualize individual KIF1A motor molecules and their movement characteristics. Our work with P305L has uncovered novel defects in KIF1A motility, providing new insights into disease-causing mutations that will inform therapeutic efforts. Additionally, the work has uncovered a novel mechanism of disease, which we find is conserved in other classes of kinesin motors that are also mutated in hereditary spastic paraplegia (HSP). Thus, our work on KIF1A is providing novel insights into other causes of understudied human diseases. In addition, we are expanding our efforts to characterize other known KIF1A mutations. Our platform for single molecule investigation will allow us to provide a more complete understanding of how each human mutation affects the KIF1A motor’s ability to move along microtubules, thus helping to tailor specific treatments for individual patients.

Recent Research

  • A Highly Conserved 310-Helix Within the Kinesin Motor Domain is Critical for Kinesin Function and Human Health (2020)
  • Disease-associated mutations hyperactivate KIF1A motility and anterograde axonal transport of synaptic vesicle precursors (2019

Barinka Lab

Cyril Barinka is a Principal Investigator at Institute of Biotechnology of the Czech Academy of Sciences, Vestec, Czech Rep, and a scientific collaborator with HNF Pharma Inc. He is a leading expert in the biochemistry and structure-function of the histone deacetylase (HDAC) enzyme gene family. Specifically, inhibitors of the HDAC6 isoform are hypothesized to represent an effective drug therapy for KIF1A Associated Neurological Disorder (KAND). This hypothesis is strongly supported by basic biology and preclinical effectiveness demonstrated for HDAC6 inhibition in Charcot-Marie-Tooth (CMT) by HNF Pharma Inc and other researchers. CMT is a hereditary peripheral nervous system (PNS) neuropathy that appears to be closely relatable to KIF1A which affects the central nervous system (CNS). HNF Pharma Inc is developing HDAC6 drugs for CMT and also supporting the work conducted by The Jackson Laboratory to prove this therapeutic mechanism of action by providing the novel brain penetrant HDAC6 inhibitor WT36-87 for testing in the KIF1A leg-dragger mouse model. Cyril is providing expertise and assay technology critical to assessing the effectiveness of WT36-87 and advancing HDAC6 drug therapies to KIF1A and CMT patients.

Recent Research

  • The disordered N-terminus of HDAC6 is a microtubule-binding domain critical for efficient tubulin deacetylation (2020)

Albany Molecular Research Inc. (AMRI)

In 2020, KIF1A.ORG was awarded a Rising Tides grant from The Child Neurology Foundation to support organizations during the COVID-19 pandemic. This grant enabled KIF1A.ORG to partner with Albany Molecular Research Inc. (AMRI) to diversify our research strategy. AMRI is a distinguished contract research organization (CRO) with multiple locations and a range of services that support therapeutic development. Our first project with AMRI is an in silico docking study to support KIF1A.ORG’s drug repurposing therapeutic development strategy. Through this project, AMRI will model the KIF1A crystal structure to understand the location and possible effects of known gain-of-function and loss-of-function mutations, and explore existing kinesin binding compounds. These efforts will provide insight into assay design and strategies to pursue additional mutations.
