SEMA3B (human)

Overview SEMA3B Inhibits axonal extension by providing local signals to specify territories inaccessible for growing axons. Expressed abundantly but differentially in a variety of neural and nonneural tissues. Belongs to the semaphorin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB. Protein type: Secreted; Secreted, signal peptide; Cell development/differentiation; Motility/polarity/chemotaxis Cellular Component: membrane; endoplasmic reticulum; extracellular region Molecular Function: receptor activity Biological Process: axon guidance; cell-cell signaling Reference #:  Q13214 (UniProtKB) Gene Symbols: SEMA3B Molecular weight: 83,122 Da Basal Isoelectric point: 9.17  Predict pI for various phosphorylation states Protein-Specific Antibodies or siRNAs from Cell Signaling Technology®
