標靶描述

Sterol regulatory element-binding protein 1 (UniProt: P36956; also known as SREBP-1, Class D basic helix-loop-helix protein 1, bHLHd1, Sterol regulatory element-binding transcription factor 1) is encoded by the SREBF1 (also known as BHLHD1, SREBP1) gene (Gene ID: 6720) in human. SREBP-1 is a multi-pass membrane protein found on nuclear, endoplasmic reticulum, and Golgi membranes. It attaches to membranes via two hydrophobic sequences (aa 477-497 and 536-556). It is expressed in a wide variety of tissues but is most abundant in liver and adrenal gland. SREBP-1 has two cytoplasmic domains (aa 1-487 and 569-1147), two transmembrane domains (aa 88-508 and 548-568), and one lumenal domain (aa 509-547). In the precursor form, which has a hairpin orientation in the membrane, both the N-terminal transcription factor domain and the C-terminal regulatory domain face the cytoplasm. Two separate site-specific proteolytic cleavages are required for release of the transcriptionally active N-terminal domain. These cleavages are carried out by two distinct proteases, called site-1 protease (S1P; aa 490-491) and site-2 protease (S2P; aa 530-531). It serves as a transcriptional activator that is essential for lipid homeostasis and regulates transcription of the LDL receptor gene. It is also involved in fatty acid and cholesterol synthesis. It acts by binds to the sterol regulatory element 1 (SRE-1) (5′-ATCACCCCAC-3′) and displays dual sequence specificity binding to both an E-box motif (5′-ATCACGTGA-3′) and to SRE-1 (5′-ATCACCCCAC-3′). SREBP-1 can be phosphorylated by AMPK at Ser402, which suppress its processing and nuclear translocation, and thereby repress target gene expression. Six isoforms of SREBP-1 have been described that are produced by alternative splicing. Isoform SREBP-1C predominates in liver, adrenal gland, and ovary, whereas isoform SREBP-1A predominates in hepatoma cell lines. Both isoforms are found in kidney, brain, white fat, and muscle. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

外觀

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

重構

300 µg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

儲存和穩定性

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
