Alternative Name(s):

hamp; Hepcidin

Species: (Organism)

Larimichthys crocea (Large yellow croaker) (Pseudosciaena crocea)

Gene Names:

hamp

Tag info:

Tag-Free

Target Protein AA Sequence:

RCRFCCRCCPRMRGCGICCRF

Expression Region:

65-85aa

Subcellular Location:

Secreted

Tissue Specificity:

Expressed in all tissues tested, with highest levels of expression in kidney and lowest levels in liver. Intra-peritoneal injection of lipopolysaccharide results in increased expression in heart, spleen and stomach, but not in kidney or liver.

Protein Length:

Full Length of Mature Protein

Pathway:

Mol. Weight:

2.5 kDa

Purity:

Greater than 90% as determined by SDS-PAGE.

Form:

Liquid or Lyophilized powder

Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Immunology

Function:

Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages (By similarity).

Involvement in disease:

Relevance:

Seems to act as a signaling molecule involved in the maintenance of iron homeostasis. Seems to be required in conjunction with HFE to regulate both intestinal iron absorption and iron storage in macrophages Has very strong antibacterial activity against the marine Gram-negative bacteria V.alginolyticus (MIC=24 µM), V.fluvialis, V.harveyis (MIC=12 µM) and V.parahaemolyticus (MIC=6 µM). Has antibacterial activity against the Gram-negative bacteria A.hydrophila (MIC=6 µM), E.coli (MIC=24 µM), and E.coli BL21(DE3)plysS (MIC=6 µM), and the Gram-positive bacteria B.cereus (MIC=24 µM), B.subtilis (MIC=6 µM), C.glutamicum (MIC=3 µM), M.luteus (MIC=3 µM), M.lysodeikticus, S.aureus (MIC=6 µM) and S.epidermis (MIC=12 µM). Possesses antifungal activity against A.niger (MIC=24 µM), F.graminearum (MIC24 µM) and F.solani (MIC=24 µM), but lacks antifungal activity against the yeasts P.pastoris GS115 and C.albicans.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
