Alternative Name Alpha-Internexin
Background Alpha-internexin is a Class IV intermediathee filament originally discovered as it copurifieswith other neurofilament subunits (1). On SDSPAGE gels it runs with an apparent molecular weight of 64 to 66 kDa, with somespecies variability, although the real molecular weight is about 55kDa, as with the otherneurofilament subunits the presence of highly negatively charged sequences results inreduction of SDS-PAGE mobility. a-internexin is related to but distinct from the betterknown neurofilament triplet proteins, NF-L, NF-M and NF-H, having similar proteinsequence motifs and a similar intron organization. It is expressed only in neurons and inlarge amounts early in neuronal development, but is downregulated in many neurons asdevelopment procedes. Many classes of mature neurons contain a-internexin in additionto NFL, NF-M and NF-H. In some mature neurons a-internexin is the only neurofilamentsubunit expressed. Antibodies to a-internexin are therefore unique probes to study andclassify neuronal types and follow their processes in sections and in tissue culture. Inaddition the very early developmental expression of a-internexin means its presence is anearly and convenient diagnostic feature of neuronal progenitors cells and other cellcommitted to the neuronal lineage. In addition recent studies show a marked upregulationof a-internexin during neuronal regeneration (2).
