Summary: The protein encoded by this gene contains a characteristic catalytic motif of the protein tyrosine phosphatases (PTPs) family. The PTP motif of this protein has the highly conserved arginine residue replaced by a proline residue; thus it may represent a distinct class of PTPs. Members of the PTP family are known to be signaling molecules that regulate a variety of cellular processes. This gene was preferentially expressed in both adult and fetal heart. A much lower expression level was detected in skeletal and smooth muscle tissues, and no expression was observed in other tissues. The tissue specific expression in the developing and adult heart suggests a role in regulating cardiac development and differentiation. [provided by RefSeq, Jul 2008]

Title: Progressive Structural Defects in Canine Centronuclear Myopathy Indicate a Role for HACD1 in Maintaining Skeletal Muscle Membrane Systems.
Labrador retrievers carrying two copies of a unique canine HACD1 loss-of-function allele that recently disseminated worldwide, are all affected by a congenital myopathy, confirming its role in muscle development.
Title: Centronuclear myopathy in Labrador retrievers: a recent founder mutation in the PTPLA gene has rapidly disseminated worldwide.
A loss-of-function mutation in the canine ortholog of HACD1 that was identified by genetic mapping in a French pedigree of Labrador retrievers causes a congenital myopathy named centronuclear myopathy (CNM) in Labrador retrievers.
Title: SINE exonic insertion in the PTPLA gene leads to multiple splicing defects and segregates with the autosomal recessive centronuclear myopathy in dogs.
Mutations in HACD1 can result in myopathies in humans; knockout mice lacking Hacd1 develop myopathic phenotypes. Data (including data from studies using knockout mice and cultured cells from knockout mice) suggest that HACD1 and HACD2 exhibit overlapping substrate specificities and thus appear to represent redundant activities in skeletal muscle.
Title: The 3-hydroxyacyl-CoA dehydratases HACD1 and HACD2 exhibit functional redundancy and are active in a wide range of fatty acid elongation pathways.
These data indicate that HACD1 is necessary for muscle function.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
