Scientific Data

Western Blot Detection of Human FHL1 antibody by Western Blot. View Larger

Detection of Human FHL1 by Western Blot. Western blot shows lysates of SH-SY5Y human neuroblastoma cell line. PVDF Membrane was probed with 1 µg/mL of Goat Anti-Human FHL1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5938) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for FHL1 at approximately 34 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: FHL1

FHL1 (Four-and-a-half LIM domains protein 1; also SLIM1 and KyoT1) is a 36 kDa member of the four-and-a half class of the LIM domain-only protein family. It is highly expressed in myocardium and skeletal muscle, and is now known to bind NFATc1, promoting muscle hypertrophy. It is also noted to be a RIP140 binding partner that inhibits estrogen receptor signaling. Human FHL1 is 323 amino acids (aa) in length. It contains one C4-type Zn-finger region (aa 7-31), three distinct LIM domains (aa 40-77; 101-158; 162-212) and a bipartite NLS (aa 231-246). There is one 32 kDa splice variant that shows a 50 aa substitution for aa 231-323. This creates a fourth LIM domain. There are also alternative start sites 29 aa and 16 aa upstream of the standard site, a deletion of aa 168-296, and an 11 aa substitution for aa 81-91. Over aa 93-166, human FHL1 is 97% aa identical to mouse FHL1.
