HORSE_AND_IGHG: A Custom Equus caballus Proteomics FASTA Database with Equine Immunoglobulin Heavy-Chain Sequences

Equus caballus protein-sequence FASTA database designed for horse proteomics database searching, with additional emphasis on immunoglobulin heavy-chain/gamma-related sequences.This dataset contains a custom protein-sequence FASTA database for Equus caballus proteomics analysis. The database comprises 75,527 protein sequence entries and 44,917,566 amino-acid residues. Most entries are UniProtKB records for horse proteins, including 75,203 UniProtKB/TrEMBL entries and 292 UniProtKB/Swiss-Prot entries. The database also includes 32 additional partial horse immunoglobulin heavy-chain sequences, including immunoglobulin mu heavy-chain and immunoglobulin gamma heavy-chain constant-region sequences. This FASTA file was prepared as a search database for mass-spectrometry-based proteomics workflows, including peptide-spectrum matching, protein identification, and characterization of equine immunoglobulin-containing samples.专为马蛋白质组学数据库检索构建的家马（Equus caballus）蛋白质序列FASTA数据库，重点补充了免疫球蛋白重链/γ相关序列。本数据集包含用于家马蛋白质组学分析的定制化蛋白质序列FASTA数据库。该数据库共计包含75527条蛋白质序列条目与44917566个氨基酸残基。绝大多数条目为马蛋白质的通用蛋白质知识库（UniProtKB）记录，其中包含75203条UniProtKB/TrEMBL条目与292条UniProtKB/Swiss-Prot条目。该数据库还额外收录了32条家马免疫球蛋白重链部分序列，涵盖免疫球蛋白μ重链与免疫球蛋白γ重链恒定区序列。本FASTA文件专为基于质谱的蛋白质组学分析流程构建检索数据库，可用于肽段-谱图匹配、蛋白质鉴定，以及含马免疫球蛋白样本的表征分析。
