This domain is found in Saccharomyces cerevisiae protein SMP2, proteins with an N-terminal lipin domain (Pfam: PF04571) and phosphatidylinositol transfer proteins . SMP2 (also known as PAH1) is involved in plasmid maintenance and respiration  and has been identified as a Mg2+-dependent phosphatidate phosphatase ( EC:18.104.22.168) that contains a haloacid dehalogenase (HAD)-like domain . Lipin proteins are involved in adipose tissue development and insulin resistance .

InterPro entry IPR013209
This domain is found in Saccharomyces cerevisiae (Baker's yeast) protein SMP2, proteins with an N-terminal lipin domain (INTERPRO) and phosphatidylinositol transfer proteins [PUBMED:8437575]. SMP2 is involved in plasmid maintenance and respiration [PUBMED:12376568]. Lipin proteins are involved in adipose tissue development and insulin resistance [PUBMED:11792863].

We make a range of alignments for each Pfam-A family:
- the curated alignment from which the HMM for the family is built
- the alignment generated by searching the sequence database using the HMM
- Representative Proteomes (RPs) at 15%, 35%, 55% and 75% co-membership thresholds
- alignment generated by searching the NCBI sequence database using the family HMM
- alignment generated by searching the metagenomics sequence database using the family HMM
You can see the alignments as HTML or in three different sequence viewers:
- Pfam viewer
- an HTML-based viewer that uses DAS to retrieve alignment fragments on request
