Tissue specificity：Higher expression in heart, also detected in kidney, stomach, testes, and skin but only weakly in lung, skeletal muscle, small intestine, and thymus. Expressed specifically and predominantly in the periodontal ligament (PDL). During tooth development, strong expression is seen in the dental follicle, which is the progenitor tissue that forms cementum, alveolar bone, and the PDL. Expressed in the perichondria of the maxilla, mandible, vertebrae, and long bones. Predominantly expressed in the perichondrium/periosteum of long bones (at protein level). {ECO:0000269|PubMed:17522060, ECO:0000269|PubMed:17804408}.
Induction：By TGFB1. Induction requires ALK5 kinase activity and SMAD3. {ECO:0000269|PubMed:17804408}.
Developmental stage：At 12.5 dpc, it is present in the mandibular as well as maxillary components of the first branchial arch. Also detected in the thoracic body wall adjacent to the heart. At 13.5 dpc, it is detected in the mesenchyme lateral to Meckel's cartilage. Pronounced expression is observed in the perichondrium of the humerus, ribs, and scapula. At 14.5 dpc, it is detected in the mesenchymal condensations lateral to Meckel's cartilage, in the perichondrium surrounding the central cartilaginous elements of the vertebra and also in the dermal mesenchyme. At 15.5 dpc, it is expressed in the perichondrium/periosteum of the long bones (i.e. femur, tibia, and fibula), some of the flat bones at the base of the skull (i.e. sphenoid bone), ribs, clavicle, and vertebrae. Also detected in the intramembranous bones of the maxilla and mandible (alveolar bone) and a strong expression is observed in sagittal sections of the subcutaneous muscles or panniculus carnosus of the thorax, trunk, and head/ neck (platysma muscle) region. Very little expression is detected in the major parenchymal organs (with the exception of the large bronchi of the lung). Its expression is prominent in the developing mouse skeleton, particularly in the perichondrium/periosteum of cartilage/bone, and is also found in other specialized connective tissues such as tendon, sclera, the connective tissue sheath surrounding muscle and dermis. In the sclera of the eye it is first detected at 15.5 dpc and stronger expression was detected at 17.5 dpc. {ECO:0000269|PubMed:11152695}.
Protein families：Small leucine-rich proteoglycan (SLRP) family, SLRP class I subfamily
