Scientific Data Images for Human Numb Antibody [Biotin]

Numb in RT‑4 Human Cell Line.

Numb was detected in immersion fixed RT‑4 human urinary bladder transitional cell papilloma cell line using Sheep Anti-Human Numb Biotinylated Antigen Affinity-purified Polyclonal Antibody (Catalog # BAF4338) at 5 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Streptavidin (red; NL999) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm. Staining was performed using our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: Numb

Numb is a member of a family of cytoplasmic adaptor proteins termed CLASPS (Clathran-associated Sorting Proteins). These link transmembrane cargo proteins to the endocytic machinery. Numb, a conserved cell-fate determining factor, is normally associated with the basolateral surface of polarized cells. Movement towards the apical surface induces its phosphorylation, which precludes its entry into this region. Human Numb is 651 amino acids (aa) in length. It contains one PTB (aa 24‑172) and one PRR (aa 366‑413) domain. There is a potential for multiple alternate splice forms that involve all regions of the molecule. Over aa 356‑592, human Numb shares 88% and 90% aa identity with mouse and canine Numb, respectively.
