May participate in the maintenance of segment identity in the hindbrain and pituitary development, and maturation or maintenance of the overall structure of the nervous system. May function as a regulatory subunit of ion channels.
Belongs to the neuronatin family.
Abundant in 18-24 week old fetal brain. Postnatally its expression decline and only minimal levels were present in adulthood.

ab27266 at 1/1000 staining human pituitary cells by IHC-P
The antibody was tested on normal human pituitary slide sections (formalin fixed/paraffin embedded). This gave good staining over a range of concentrations with a microwave/pressure antigen retrieval step. Staining was strongly associated with the cell membrane and blocked by incubating with the neuronatin antibody with the peptide which the antibody was raised against.
ICC/IF image of ab27266 stained SKNSH cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab27266, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Immunohistochemical analysis of PFA-perfusion fixed mouse brain tissue, staining Neuronatin with ab27266.
Tissue was post-fixed in 4% paraformaldehyde overnight at 4°C. Sections were incubated in a blocking buffer of 0.3% Triton-X-100, 1% BSA and 10% NGS in PBS for 2 hours at room temperature, before incubating with primary antibody (1/100) for 2 days at 4°C. An AlexaFluor®-conjugated anti-rabbit IgG (1/1000) was used as the secondary antibody.
