Scientific Data

Western Blot Detection of Human TFCP2L1 antibody by Western Blot. View Larger

Detection of Human TFCP2L1 by Western Blot. Western blot shows lysates of human placental tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human TFCP2L1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5726) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF019). A specific band was detected for TFCP2L1 at approximately 54 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 8.

Background: TFCP2L1

TFCP2L1 (Transcription factor CP2‑like protein # 1; also LBP‑9) is a 54 kDa (predicted) member of the CP2 subfamily, grh/CP2 family of proteins. It is expressed in placental synctiotrophoblast cells, and regulates the production of CYP11A1/P450scc. P450scc is a cholesterol cleavage enzyme that generates pregnenolone, a necessary intermediate in the formation of progesterone. TFCP2L1 both positively and negatively regulates P450scc synthesis through homodimerization and heterodimerization with LBP‑1b. Human TFCP2L1 is 479 amino acids (aa) in length. It contains a transcriptional repressor region (aa 100‑200) and a dimerization domain (aa 300‑479). There is one splice variant that shows a deletion of aa 400‑464. Human TFCP2L1 is 73% aa identical to human TFCP2, and 93% aa identical to mouse CRTR‑1, a closely related molecule that may not represent the actual mouse ortholog to TFCP2L1.
