Rabbit Anti-CD9/FITC Conjugated antibody
background:
CD9 antigen is a glycoprotein expressed on the surface of developing B lymphocytes, platelets, monocytes, eosinophils, basophil, stimulated T lymphocytes and by neurons and glial cells in the peripheral nervous system. It belongs to a family of membrane proteins termed tetraspanins which transverse the membrane four times. In pre B cells and platelets, CD9 antigen regulates cell activation and aggregation possibly through an association with the integrin CD41 / CD61 (GPIIb / GPIIIa). It also regulates cell motility in a variety of cell lines, and appears to be an important regulator of Schwann cell behaviour in peripheral nerve.
Function:
Involved in platelet activation and aggregation. Regulates paranodal junction formation. Involved in cell adhesion, cell motility and tumor metastasis. Required for sperm-egg fusion.
Subunit:
Forms both disulfide-linked homodimers and higher homooligomers as well as heterooligomers with other members of the tetraspanin family. Associates with CR2/CD21 and with PTGFRN/CD9P1. Interacts directly with IGSF8.
Subcellular Location:
Membrane; Multi-pass membrane protein.
Tissue Specificity:
Expressed by a variety of hematopoietic and epithelial cells.
Post-translational modifications:
Protein exists in three forms with molecular masses between 22 and 27 kDa, and is known to carry covalently linked fatty acids.
Similarity:
Belongs to the tetraspanin (TM4SF) family.

CD9是一种普遍存在于细胞膜表面属于四跨膜超蛋白家族的细胞表面糖蛋白, 参与质膜的融合过程，在细胞膜生物学中发挥重要作用。
近年来经研究发现，CD9与多种肿瘤转移有关，故称肿瘤转移抑制基因亦称抗肿瘤转移基因。是一个新的肿瘤转移抑制基因膜运动相关蛋白-1(CD9/MRP-1)，其分子功能还有待于进一步研究。CD9主要在早B细胞、活化T淋巴细胞、嗜酸性粒细胞、嗜碱性粒细胞和血小板表达。
