Lm1

Mus musculus

PHENOTYPE: This locus controls an antigen present on thymocytes, T lymphoblasts, some plasmacytomas and some myeloid cells. The a allele determines the Lm-1.1 specificity in BALB/c strain; the b allele determines Lm-1.2 in C57BL/6, NZB, C.B-17, C.B-23 and C.B-26. [provided by MGI curators]

Hic1

Homo sapiens

This gene functions as a growth regulatory and tumor repressor gene. Hypermethylation or deletion of the region of this gene have been associated with tumors and the contiguous-gene syndrome, Miller-Dieker syndrome. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Sep 2010]

Pfn1

Homo sapiens

This gene encodes a member of the profilin family of small actin-binding proteins. The encoded protein plays an important role in actin dynamics by regulating actin polymerization in response to extracellular signals. Deletion of this gene is associated with Miller-Dieker syndrome, and the encoded protein may also play a role in Huntington disease. Multiple pseudogenes of this gene are located on chromosome 1.

BCYRN1

Homo sapiens

This gene, which encodes a neural small non-messenger RNA, is a member of the family of interspersed repetitive DNA, and its product represents an example of a primate tissue-specific RNA polymerase III transcript. The RNA sequence is divided into three domains: a 5' portion homologous to the Alu Lm, a central adenosine-rich region, and the terminal 43-nt nonrepetitive domain. It is believed that this gene was retropositionally generated and recruited into a function regulating dendritic protein biosynthesis. At least two pseudogenes of this gene have been identified.

Pafah1b1

Homo sapiens

This locus was identified as encoding a gene that when mutated or lost caused the lissencephaly associated with Miller-Dieker lissencephaly syndrome. This gene encodes the non-catalytic alpha subunit of the intracellular Ib isoform of platelet-activating factor acteylhydrolase, a heterotrimeric enzyme that specifically catalyzes the removal of the acetyl group at the SN-2 position of platelet-activating factor (identified as 1-O-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine). Two other isoforms of intracellular platelet-activating factor acetylhydrolase exist: one composed of multiple subunits, the other, a single subunit. In addition, a single-subunit isoform of this enzyme is found in serum. [provided by RefSeq, Apr 2009]
