The sequence of the target protein is listed below. MNGYY MVGMSVLQCE LNGNGDAFWN GHPPSCKKVY CLPPPKIKNG THTFTDIKVF KYHEAVIYSC DPNPGPDKFS LVGPSMLFCA GHNTWSSDPP ECKVVKCPFP VLQNGRQISR TEKKFSYQAL VLFQCLEGFY MEGSSMVVCG AKSSWEPSIP QCLKGPKPHS TKPPVYSESG YPSPREGIFG QEFDAWIIAL IVVTSVVGVI V
form :
Supplied as lyophilized form in 20mM Tris, 500mM NaCI, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% sarcosyl, 5% trehalose, and preservative.
storage stability :
Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months. Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.

ncbi summary :
may be involved in fertilization or reproduction; human homolog acts as an inhibitor of plasma membrane complement [RGD, Feb 2006]
uniprot summary :
Function: May be involved in the fusion of the spermatozoa with the oocyte during fertilization. Ref.2 Ref.3. Subcellular location: Cytoplasmic vesicle secretory vesicle acrosome inner membrane; Single-pass membrane protein. Note: Inner acrosomal membrane of spermatozoa. Ref.3. Tissue specificity: Specifically expressed in testis. Within testis, present only in elongated spermatids and spermatozoa (at protein level). Ref.1 Ref.2 Ref.3. Developmental stage: Not expressed in embryonic and immature rats. Expressed in parallel with synthesis of spermatids. Ref.3. Post-translational modification: O-glycosylated. Ref.3N-glycosylated. Ref.3. Sequence similarities: Contains 4 Sushi (CCP/SCR) domains.
