PIGR: Immunoglobulin Domain Alignments for Evolutionary Analysis

Immunoglobulin (Ig) domain sequences extracted from the polymeric immunoglobulin receptor (PIGR) protein have been aligned. The dataset is 38.2 KB in size and was authored by Huang. It was last updated on 2026-04-28.

Use Cases

• Conduct evolutionary analysis based on aligned immunoglobulin domain sequences.
• Train models for protein domain classification based on sequence alignments.
• Study sequence conservation patterns within the PIGR protein.
• Perform phylogenetic analysis of immunoglobulin domains.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• File size is precisely known to be 38.2 KB.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
