Immunofluorescent analysis of FGFR4/CD334 in HeLa cells using a FGFR4/CD334 polyclonal antibody (Product # PA1-31991). Cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min) and incubated with primary antibody ata dilution of 1:200 for 2 hrs at room temperature. Detection was performed using an Alexa Fluor 488 conjugated donkey anti-rabbit secondary antibody (green) at a dilution of 1:1000 for 1 hr. Nuclei were counterstained with Hoechst 33342 (blue) (10 µg/ml, 5 min).

Protein kinases are enzymes that transfer a phosphate group from a phosphate donor, generally the g phosphate of ATP, onto an acceptor amino acid in a substrate protein. By this basic mechanism, protein kinases mediate most of the signal transduction in eukaryotic cells, regulating cellular metabolism, transcription, cell cycle progression, cytoskeletal rearrangement and cell movement, apoptosis, and differentiation. With more than 500 gene products, the protein kinase family is one of the largest families of proteins in eukaryotes. The family has been classified in 8 major groups based on sequence comparison of their tyrosine (PTK) or serine/threonine (STK) kinase catalytic domains. The tyrosine kinase (TK) group is mainly involved in the regulation of cell-cell interactions such as differentiation, adhesion, motility and death. There are currently about 90 TK genes sequenced, 58 are of receptor protein TK (e.g. EGFR, EPH, FGFR, PDGFR, TRK, and VEGFR families), and 32 of cytosolic TK (e.g. ABL, FAK, JAK, and SRC families).
