Description

LIN-36 Protein in C. elegans: A Cell-Cycle Regulator

LIN-36 is a C. elegans THAP domain protein critical for cell-cycle regulation and germline development. It functions as part of the DREAM (DP, E2F, and MuvB) complex, which represses cell-cycle genes and maintains quiescence. Key findings include:

Mechanistic Roles

FunctionDetailsSource
Cell-cycle repressionLIN-36 promotes DREAM binding to classical cell-cycle targets (e.g., cdc-14, cki-1) and enriches H2A.Z histone variants in gene bodies.
Germline-specific repressionLIN-15B (a paralog of LIN-36) represses germline-specific genes in the soma via H3K9me2 promoter marking.
Genetic interactionsLoss of LIN-36 enhances intestinal hyperproliferation phenotypes in lin-35 (Rb homolog) or cdc-14 (Cdc14 phosphatase) mutants.

LIN-36 and LIN-15B exhibit distinct genomic binding patterns:

  • LIN-36: Overlaps with LIN-35 at 95% of peaks, enriched in cell-cycle genes.

  • LIN-15B: Overlaps with LIN-35 at 72% of peaks, enriched in germline-specific genes.

L-35/L-36 Antigens in Human T Cells

In human immunology, monoclonal antibodies L-35 and L-36 define novel T cell activation antigens expressed on both CD4⁺ and CD8⁺ subsets. These markers are absent on resting T cells but appear after mitogen stimulation.

Antibodies Targeting IL-36 or Connexin 36

While no direct references to "LIN-36 antibodies" exist, antibodies against IL-36 family members or Connexin 36 are well-characterized:

IL-36 α/β/γ Antibodies

TargetAntibodyKey FindingsSource
IL-36α (IL-1F6)MAB10781 (Rabbit)Neutralizes IL-36α-induced CXCL8/IL-8 secretion in A431 cells (ND₅₀: 0.2–1.2 µg/mL). Detects a 15 kDa band in Western blots.
IL-36R (receptor)MAB92 (Mouse)Blocks IL-36α/β/γ signaling in keratinocytes; binds IL-36R domain 2 (residues 9–14, 96–110, etc.).

Connexin 36 Antibody

TargetAntibodyKey FindingsSource
Connexin 36 (GJA9/GJD2)36-4600 (Polyclonal)Identifies a 36 kDa band in mouse brain/retina lysates. Used in zebrafish studies of electrical synapses.

Epigenetic Markers: H3K36me3 Antibodies

Though unrelated to LIN-36, antibodies targeting histone modifications (e.g., H3K36me3) are clinically relevant. For example:

Target Background

Function
This antibody targets LIN-36, a protein essential for negatively regulating vulval development in nematodes. LIN-36 functions by antagonizing Ras-mediated vulval induction, acting autonomously within individual cells.
