-20°C

Supplied as a liquid in PBS, pH 7.2, 0.02% sodium azide.

XKSPYK domain [SPEKAKSPEKAKSC ] of NFH.

The human heavy neurofilament subunit (NFH) tail that contains a repeated motif, XKSPYK. Deletions in this repeat region are strongly implicated as a primary event in amyotrophic lateral sclerosis.


Neurofilaments can be defined as the intermediate or 10 nm filaments found in specifically in neuronal cells. In the electron microscope neurofilaments appear as 10 nm diameter fibres of indeterminate length which generally have fine wispy protrusions from their sides. They are found particularly abundantly in axons of large projection neurons. They probably function to provide structural support for neurons and their synapses and to support the large axon diameters required for rapid conduction of impulses down axons. They are composed a mixture of subunits which usually include the three neurofilament triplet proteins known as NFL, NFM and NFH. Neurofilaments may also include smaller amounts of peripherin, alpha internexin, nestin and in some cases vimentin. Antibodies to the various neurofilament subunits are very useful cell type markers since the proteins are among the most abundant of the nervous system, are expressed only in neurons and are biochemically very stable.
