The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/500 - 1/1000. Detects a band of approximately 40 kDa (predicted molecular weight: 45 kDa).
FunctionInvolved in early steps of centriole duplication, as well as in the later steps of centriole length control. Required for ciliogenesis.
Involvement in diseaseDefects in POC1A are the cause of short stature, onychodysplasia, facial dysmorphism, and hypotrichosis (SOFT) [MIM:614813]. A syndrome characterized by severely short long bones, peculiar facies associated with paucity of hair, and nail anomalies. Growth retardation is evident on prenatal ultrasound as early as the second trimester of pregnancy, and affected individuals reach a final stature consistent with a height age of 6 years to 8 years. Relative macrocephaly is present during early childhood but head circumference is markedly low by adulthood. Psychomotor development is normal. Facial dysmorphism includes a long, triangular face with prominent nose and small ears, and affected individuals have an unusual high-pitched voice. Clinodactyly, brachydactyly, and hypoplastic distal phalanges and fingernails are present in association with postpubertal sparse and short hair. Typical skeletal findings include short and thick long bones with mild irregular metaphyseal changes, short femoral necks, and hypoplastic pelvis and sacrum. All long bones of the hand are short, with major delay of carpal ossification and cone-shaped epiphyses. Vertebral body ossification is also delayed. Note=Cells derived from affected individuals have abnormal mitotic mechanics with multipolar spindles, in addition to clearly impaired ciliogenesis.
Sequence similaritiesBelongs to the WD repeat POC1 family. Contains 7 WD repeats.
Cellular localizationCytoplasm > cytoskeleton > centrosome > centriole. Cytoplasm > cytoskeleton > cilium basal body. Component of both mother and daughter centrioles.
