De novo transcriptome assembly and functional annotation of the Antarctic sea anemone Urticinopsis antarctica

This dataset contains the curated de novo transcriptome assembly and associated functional annotation of the Antarctic sea anemone Urticinopsis antarctica. The final assembly comprises 124,184 transcripts and was generated by merging Trinity and SPAdes assemblies following the Oyster River Protocol. Assembly completeness assessed with BUSCO (Metazoa dataset) yielded 98.3% complete BUSCOs. The annotation table contains 90,790 annotation records corresponding to 71,920 uniquely annotated transcripts. Functional annotations include UniProt-SwissProt, Pfam domain assignments, OrthoDB orthology, and Gene Ontology (GO) terms. Raw sequencing reads are available in the NCBI Sequence Read Archive under BioProject accession PRJNA1285170. Files included:1. Final transcriptome assembly (FASTA)2. Functional annotation table (TSV)3. Immune/stress-related summary table4. Pfam family counts summary
