Functional Description
| Product Code | Frontend Short Summary | Detailed Biological Function Description | Applicable Research Areas (comma-separated) | Targets / Pathways |
| PEP-HOXB7-01 | 18-aa peptide corresponding to human homeobox transcription factor HOXB7 (UniProt P09629) residues 8-25 (sequence NTLFSKYPASSSVFATGA), an N-terminal non-homeodomain fragment; used in HOXB7 tumor-associated antigen / HLA epitope and developmental transcriptional-regulation studies. | HOXB7 (homeobox protein Hox-B7, UniProt P09629) is a sequence-specific transcription factor of the Antp homeobox family, critical for embryonic anterior-posterior patterning, organ development and hematopoiesis; it is aberrantly overexpressed in breast, ovarian and melanoma and other tumors, promoting proliferation, angiogenesis and invasion, and is regarded as a candidate tumor-associated antigen / HLA-restricted epitope. This product is residues 8-25 (NTLFSKYPASSSVFATGA) of the 217-aa human HOXB7 chain (N-terminus MSSLYYA…), lying in the N-terminal non-homeodomain region (the homeobox DNA-binding domain is at 137-196). It is used for prediction and validation of HOXB7-derived HLA epitopes, tumor immune-peptide library screening, antibody/reagent development, and studies of HOXB7 N-terminal interactions. Sequence basis: UniProt P09629 full-length human HOXB7; residues 8-25 agree with the TargetMol catalog (NTLFSKYPASSSVFATGA). Note: some suppliers (Amerigo / NovoPro) list a 15-mer PLLLKLLKSVGAQKD that does not match the P09629 human sequence; this product follows UniProt P09629 numbering. | Tumor immunology, HLA epitope prediction/validation, embryonic development, homeobox transcription factor, breast/ovarian/melanoma research, peptide library screening | HOXB7 protein (UniProt P09629); HLA-I/II presentation; PBX1 interaction |
