PAFAH1B1 (Platelet activating factor acetyl hydrolase 1b regulatory subunit 1) encodes a protein referred to as Lis1. It is located on the chromosome location 17p13.3. The gene spans ~92 kb at the genomic level. It consists of a N-terminal coiled-coil domain and seven WD40 repeats at the C-terminus end.
Immunogen

Application
Anti-LIS1/PAFAH1B1 antibody produced in goat is suitable for indirect ELISA and western blot applications.
Biochem/physiol Actions
PAFAH1B1 (Platelet activating factor acetyl hydrolase 1b regulatory subunit 1) majorly participates in the neuronal migration pathway during brain development. It is a non-catalytic regulatory subunit of platelet activating factor (PAF) acetyl hydrolase 1b (Pafah1b) complex. During neuronal migration, it conjugates with PAFAH1B2 and PAFAH1B3 to control the concentration of platelet activating factor in the brain. Deleted gene expression of PAFAH1B1 has been reported in the 7p13.3 deletion syndrome or Miller-Dieker syndrome with mental retardation and facial dysmorphism. Heterozygous mutations of the gene cause type 1 lissencephaly characterized with impaired neuronal migration and reduction in the number of cortical gyri.

The development of the cerebral cortex involves a series of dynamic events, including cell proliferation and migration, which rely on the motor protein dynein and its regulators NDE1 and NDEL1. While the loss of function in NDE1 leads to microcephaly-related

The 17p13.3 deletion syndrome (or Miller-Dieker syndrome, MDS, MIM 247200) is characterized by lissencephaly, mental retardation and facial dysmorphism. The phenotype is attributed to haploinsufficiency of two genes present in the minimal critical region of MDS: PAFAH1B1 (formerly referred to
Reelin, an extracellular protein that signals through the Dab1 adapter protein, and Lis1 regulate neuronal migration and cellular layer formation in the brain. Loss of Reelin and reduction in Lis1 activity in mice or humans results in the disorganization of
Genes mutated in human neuronal migration disorders encode tubulin proteins and a variety of tubulin-binding and -regulating proteins, but it is very poorly understood how these proteins function together to coordinate migration. Additionally, the way in which regional differences in
Classical lissencephaly (LIS) and subcortical band heterotopia (SBH) are related cortical malformations secondary to abnormal migration of neurons during early brain development. Approximately 60% of patients with classical LIS, and one patient with atypical SBH have been found to have
