SEMA6B

This gene encodes a member of the semaphorin family, a group of proteins characterized by the presence of a conserved semaphorin (sema) domain. Whereas some semaphorins are transmembrane proteins, others are secreted. Semaphorins play a major role in axon guidance. The protein encoded by this gene may be involved in both peripheral and central nervous system development. [provided by RefSeq]

sema domain, transmembrane domain (TM), and cytoplasmic domain, (semaphorin) 6B

Functions as a cell surface repellent for mossy fibers of developping neurons in the hippocampus where it plays a role in axon guidance. May function through the PLXNA4 receptor expressed by mossy cell axons.
(Microbial infection) Acts as a receptor for P.sordellii toxin TcsL in the in the vascular endothelium.

Epilepsy, progressive myoclonic 11 (EPM11):
A form of progressive myoclonic epilepsy, a clinically and genetically heterogeneous group of disorders defined by the combination of action and reflex myoclonus, other types of epileptic seizures, and progressive neurodegeneration and neurocognitive impairment. EPM11 is an autosomal dominant form. Clinical features include normal or mildly delayed early development, developmental regression after seizures onset, inability to walk, severely impaired intellectual development, poor or absent speech, spasticity, ataxia, and intention tremor. Brain imaging shows cerebellar atrophy in some patients.
