Product Overview
This rabbit polyclonal antibody recognizes FMR1-interacting protein NUFIP1 in human samples and is validated for Western blot, ICC/IF and ELISA. The predicted molecular weight is 56.3 kDa, and the supplier reports an observed band at about 75 kDa.
NUFIP1 (FMR1-interacting protein 1) is a nuclear RNA-binding protein originally identified as a partner of the fragile X protein FMRP. It is involved in the assembly of small nucleolar ribonucleoproteins, although its roles are not fully characterized.

Reactivity Notes
The supplier lists reactivity with human. UniProt places FMR1-interacting protein NUFIP1 in the nucleus. Tissue expression noted by UniProt (human): Expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon, peripheral blood leukocyte, heart, brain, placenta, lung, liver, skeletal muscle, kidney, and pancreas. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
