Anti-NSUN2 Antibody Picoband®

NOP2/Sun domain family, member 2 is a protein that in humans is encoded by the NSUN2 gene. This gene encodes a methyltransferase that catalyzes the methylation of cytosine to 5-methylcytosine (m5C) at position 34 of intron-containing tRNA (Leu) (CAA) precursors. This modification is necessary to stabilize the anticodon-codon pairing and correctly translate the mRNA. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

Abundantly expressed in CNS. Widely expressed at low levels. Detected in dorsal root ganglion. Expressed in the keratinocyte layers of the outer root sheath and, to lesser extent, to the matrix of the hair follicles.

Putative receptor-activated non-selective calcium permeant cation channel. It is activated by innocuous (warm) temperatures and shows an increased response at noxious temperatures greater than 39 degrees Celsius. Activation exhibits an outward rectification. May associate with TRPV1 and may modulate its activity. Is a negative regulator of hair growth and cycling: TRPV3-coupled signaling suppresses keratinocyte proliferation in hair follicles and induces apoptosis and premature hair follicle regression.
