F‑box protein 15/FBXO15 in BG01V Human Embryonic Stem Cells.
F‑box protein 15/FBXO15 was detected in immersion fixed BG01V human embryonic stem cells using Mouse Anti-Human F‑box protein 15/FBXO15 Monoclonal Antibody (Catalog # MAB6035) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007). Oct-3/4 was detected in cell nuclei using Goat Anti-Human Oct-3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759) and stained using NorthernLights™ 493-conjugated Anti-Goat IgG Secondary Antibody (green; Catalog # NL003). Specific staining of F‑box protein 15 was localized to cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.
Detection of FBXO15 in BG01V Human Stem Cells by Flow Cytometry.
BG01V human embryonic stem cells were stained with Mouse Anti-Human F‑box protein 15/FBXO15 Monoclonal Antibody (Catalog # MAB6035, filled histogram) or isotype control antibody (Catalog # MAB003, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.

Background: F-box protein 15/FBXO15
FBXO15 (F-box only protein 15; also FBX15) is a 50‑60 kDa member of the F-box family, O-subfamily of molecules that is most closely related to FBXO8 and O11. It is found in pluripotent stem cells and testis tissue, and apparently serves as a substrate recognition component of the SCF-type E3 ubiquitin ligase. Human FBXO15 (isoform 2 of accession Q8NCQ5) is 434 amino acids (aa) in length. It contains one F-box (aa 1‑41) that likely serves as an interaction domain for SKP1. There are two potential isoforms, one that contains an alternative start site 76 aa upstream of the standard site (isoform 1 of accession Q8NCQ5), and a second that shows complex splicing that includes a 66 aa insertion after Asn35, a Ser substitution for aa 186‑256, and a 106 aa substitution for aa 304‑346. Over aa 298‑434, human FBXO15 shares 53% aa identity with mouse FBXO15.
