Research Areas:Microbiology

Uniprot NO.:P60022

Uniprot Entry Name:DEFB1_HUMAN

Gene Names:DEFB1,BD1,HBD1

Species:Homo sapiens (Human)

Source:E.Coli

Expression Region:22-68aa

Sequence:GNFLTGLGHR SDHYNCVSSG GQCLYSACPI FTKIQGTCYR GKAKCCK

Protein Description:Partial

Tag Info:Tag-Free

Mol. Weight:5.1 kDa

Biological_Activity:Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using CD34+ dendritic cells is in a concentration range of 100.0-1000.0 ng/ml.

Purity:>98% as determined by SDS-PAGE and HPLC.

Endotoxin:Less than 1.0 EU/µg as determined by LAL method.

Form:Lyophilized powder

Buffer:Lyophilized from a 0.2 µm filtered 20 mM PB, pH 7.4, 130 mM NaCl

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.

Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Alternative Name/ Alias:BD-1, Defensin, beta 1

Relevance:Has bactericidal activity. {ECO:0000250}.

PubMed ID:9268634; 9070620; 15489334; 7628632; 12010514; 11486002; 11714914

Function:Has bactericidal activity. May act as a ligand for C-C chemokine receptor CCR6. Positively regulates the sperm motility and bactericidal activity in a CCR6-dependent manner. Binds to CCR6 and triggers Ca2+ mobilization in the sperm which is important for its motility

Involvement in disease:

Subcellular Location:Secreted, Membrane

Protein Families:Beta-defensin family

Tissue Specificity:Blood plasma. Sperm. Highly expressed in the lower head and midpiece of sperm. Significantly reduced levels found in the sperms of asthenozoospermia and leukocytospermia patients (at protein level).
