Acetyl-coenzyme A transporter 1 also known as solute carrier family 33 member 1 (SLC33A1) is a protein that in humans is encoded by the SLC33A1 gene. [5]
Acetyl-coenzyme A transporter 1 also known as solute carrier family 33 member 1 (SLC33A1) is a protein that in humans is encoded by the SLC33A1 gene. [5]
The protein encoded by this gene is required for the formation of O-acetylated (Ac) gangliosides. The encoded protein is predicted to contain 6 to 10 transmembrane domains, and a leucine zipper motif in transmembrane domain III. [5]
Defects in this gene have been reported to cause spastic paraplegia autosomal dominant type 42 (SPG42) in one Chinese family, but not in similar patients of European descent. [5]
Hereditary spastic paraplegia (HSP) is a group of inherited diseases whose main feature is a progressive gait disorder. The disease presents with progressive stiffness (spasticity) and contraction in the lower limbs. HSP is also known as hereditary spastic paraparesis, familial spastic paraplegia, French settlement disease, Strumpell disease, or Strumpell-Lorrain disease. The symptoms are a result of dysfunction of long axons in the spinal cord. The affected cells are the primary motor neurons; therefore, the disease is an upper motor neuron disease. HSP is not a form of cerebral palsy even though it physically may appear and behave much the same as spastic diplegia. The origin of HSP is different from cerebral palsy. Despite this, some of the same anti-spasticity medications used in spastic cerebral palsy are sometimes used to treat HSP symptoms.
Glucose transporter 1, also known as solute carrier family 2, facilitated glucose transporter member 1 (SLC2A1), is a uniporter protein that in humans is encoded by the SLC2A1 gene. GLUT1 facilitates the transport of glucose across the plasma membranes of mammalian cells. This gene encodes a major glucose transporter in the mammalian blood-brain barrier. The encoded protein is found primarily in the cell membrane and on the cell surface, where it can also function as a receptor for human T-cell leukemia virus (HTLV) I and II. One good source of GLUT1 is erythrocyte membranes. GLUT1 accounts for 2 percent of the protein in the plasma membrane of erythrocytes. GLUT1, found in the plasma membrane of erythrocytes, is a classic example of a uniporter. After glucose is transported into the erythrocyte, it is rapidly phosphorylated, forming glucose-6-phosphate, which cannot leave the cell. Mutations in this gene can cause GLUT1 deficiency syndrome 1, GLUT1 deficiency syndrome 2, idiopathic generalized epilepsy 12, dystonia 9, and stomatin-deficient cryohydrocytosis.

Sodium bicarbonate transporter-like protein 11 is a protein that in humans is encoded by the SLC4A11 gene.
Kinesin heavy chain isoform 5A is a protein that in humans is encoded by the KIF5A gene.
Non-imprinted in Prader-Willi/Angelman syndrome region protein 1 is a protein that in humans is encoded by the NIPA1 gene. This gene encodes a potential transmembrane protein which functions either as a receptor or transporter molecule, possibly as a magnesium transporter. This protein is thought to play a role in nervous system development and maintenance. Alternative splice variants have been described, but their biological nature has not been determined. Mutations in this gene have been associated with the human genetic disease autosomal dominant spastic paraplegia 6.
