Human Gremlin, His Tag (GR1-H52H3) is expressed from human 293 cells (HEK293). It contains AA Lys 25 - Asp 184 (Accession # NP_037504).
Predicted N-terminus: Lys 25
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 20.2 kDa. The protein migrates as 28-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with 1 mM EDTA. Normally trehalose is added as protectant before lyophilization.

Immobilized Human BMP-2, Tag Free (Cat. No. BM2-H4117) at 2 μg/mL (100 μL/well) can bind Human Gremlin, His Tag (Cat. No. GR1-H52H3) with a linear range of 0.02-0.313 μg/mL (QC tested).
Gremlin is also known as Cysteine knot superfamily 1, BMP antagonist 1 (CKTSF1B1), DAN domain family member 2 (DAND2), Down-regulated in Mos-transformed cells protein (DRM), Increased in high glucose protein 2 (IHG-2), Cell proliferation-inducing gene 2 protein (PIG2) or Gremlin-1 (GREM1), which is highly expressed in small intestine, fetal brain and colon. Gremlin / GREM-1 interacts with SLIT1 and SLIT2 in a glycosylation-dependent manner. Gremlin may play an important role during carcinogenesis and metanephric kidney organogenesis, as a BMP antagonist required for early limb outgrowth and patterning in maintaining the FGF4-SHH feedback loop. Gremlin down-regulates the BMP4 signaling in a dose-dependent manner and acts as inhibitor of monocyte chemotaxis.
