There are a number of ELISA Kits available for the measurement of filamin, beta, another term for the human protein, filamin B. Other synonyms may include: ABP-280 homolog, Larsen syndrome 1 (autosomal dominant), actin binding protein 278, actin-binding-like protein, filamin B beta, filamin homolog 1, and filamin-3. It is encoded by the FLNB gene to yield a protein 2602 amino acids in length and 278.2 kDa in size. However, there are up to 9 reported isoforms. The protein is categorized into the Filamin family. Versions of filamin, beta are present in other organisms, including: Mouse, Rat, Frog.
