BACKGROUND SOURCE Myotubularin and the myotubularin-related proteins belong to a highly con - MTMR9 (N-15) is an affinity purified goat polyclonal antibody raised against a served family of eukaryotic phosphatases that utilize inositol phospholipids, peptide mapping near the N-terminus of MTMR9 of human origin. rather than phosphoproteins, as substrates. MTMR9 (myotubularin-related protein 9), also known as C8orf9, is a 549 amino acid protein that belongs to PRODUCT the protein-tyrosine phosphatase family and non-receptor class myotubularin Each vial contains 200 µg IgG in 1.0 ml of PBS with < 0.1% sodium azide subfamily. Localizing to the cytoplasm, MTMR9 is expressed in many tis - and 0.1% gelatin. sues, including brain. MTMR9 interacts with MTMR6, MTMR7 and MTMR8. As opposed to other members of the myotubularin-related protein family, Blocking peptide available for competition studies, sc-48244 P, (100 µg MTMR9 does not contain a dual-specificity phosphatase domain, and is a peptide in 0.5 ml PBS containing < 0.1% sodium azide and 0.2% BSA). probable pseudophosphatase. Containing a double-helical motif similar to the SET interaction domain, MTMR9 may function in the control of cell APPLICATIONS pro liferation. MTMR9 (N-15) is recommended for detection of MTMR9 of mouse, rat and human origin by Western Blotting (starting dilution 1:200, dilution range REFERENCES 1:100-1:1000), immunofluorescence (starting dilution 1:50, dilution range 1.
